-// Introduction
-// ************
-//
-// The following notes assume that you are familiar with the YAML specification
-// (http://yaml.org/spec/cvs/current.html).  We mostly follow it, although in
-// some cases we are less restrictive that it requires.
-//
-// The process of transforming a YAML stream into a sequence of events is
-// divided on two steps: Scanning and Parsing.
-//
-// The Scanner transforms the input stream into a sequence of tokens, while the
-// parser transform the sequence of tokens produced by the Scanner into a
-// sequence of parsing events.
-//
-// The Scanner is rather clever and complicated. The Parser, on the contrary,
-// is a straightforward implementation of a recursive-descendant parser (or,
-// LL(1) parser, as it is usually called).
-//
-// Actually there are two issues of Scanning that might be called "clever", the
-// rest is quite straightforward.  The issues are "block collection start" and
-// "simple keys".  Both issues are explained below in details.
-//
-// Here the Scanning step is explained and implemented.  We start with the list
-// of all the tokens produced by the Scanner together with short descriptions.
-//
-// Now, tokens:
-//
-//      STREAM-START(encoding)          # The stream start.
-//      STREAM-END                      # The stream end.
-//      VERSION-DIRECTIVE(major,minor)  # The '%YAML' directive.
-//      TAG-DIRECTIVE(handle,prefix)    # The '%TAG' directive.
-//      DOCUMENT-START                  # '---'
-//      DOCUMENT-END                    # '...'
-//      BLOCK-SEQUENCE-START            # Indentation increase denoting a block
-//      BLOCK-MAPPING-START             # sequence or a block mapping.
-//      BLOCK-END                       # Indentation decrease.
-//      FLOW-SEQUENCE-START             # '['
-//      FLOW-SEQUENCE-END               # ']'
-//      BLOCK-SEQUENCE-START            # '{'
-//      BLOCK-SEQUENCE-END              # '}'
-//      BLOCK-ENTRY                     # '-'
-//      FLOW-ENTRY                      # ','
-//      KEY                             # '?' or nothing (simple keys).
-//      VALUE                           # ':'
-//      ALIAS(anchor)                   # '*anchor'
-//      ANCHOR(anchor)                  # '&anchor'
-//      TAG(handle,suffix)              # '!handle!suffix'
-//      SCALAR(value,style)             # A scalar.
-//
-// The following two tokens are "virtual" tokens denoting the beginning and the
-// end of the stream:
-//
-//      STREAM-START(encoding)
-//      STREAM-END
-//
-// We pass the information about the input stream encoding with the
-// STREAM-START token.
-//
-// The next two tokens are responsible for tags:
-//
-//      VERSION-DIRECTIVE(major,minor)
-//      TAG-DIRECTIVE(handle,prefix)
-//
-// Example:
-//
-//      %YAML   1.1
-//      %TAG    !   !foo
-//      %TAG    !yaml!  tag:yaml.org,2002:
-//      ---
-//
-// The correspoding sequence of tokens:
-//
-//      STREAM-START(utf-8)
-//      VERSION-DIRECTIVE(1,1)
-//      TAG-DIRECTIVE("!","!foo")
-//      TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
-//      DOCUMENT-START
-//      STREAM-END
-//
-// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
-// line.
-//
-// The document start and end indicators are represented by:
-//
-//      DOCUMENT-START
-//      DOCUMENT-END
-//
-// Note that if a YAML stream contains an implicit document (without '---'
-// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
-// produced.
-//
-// In the following examples, we present whole documents together with the
-// produced tokens.
-//
-//      1. An implicit document:
-//
-//          'a scalar'
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          SCALAR("a scalar",single-quoted)
-//          STREAM-END
-//
-//      2. An explicit document:
-//
-//          ---
-//          'a scalar'
-//          ...
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          DOCUMENT-START
-//          SCALAR("a scalar",single-quoted)
-//          DOCUMENT-END
-//          STREAM-END
-//
-//      3. Several documents in a stream:
-//
-//          'a scalar'
-//          ---
-//          'another scalar'
-//          ---
-//          'yet another scalar'
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          SCALAR("a scalar",single-quoted)
-//          DOCUMENT-START
-//          SCALAR("another scalar",single-quoted)
-//          DOCUMENT-START
-//          SCALAR("yet another scalar",single-quoted)
-//          STREAM-END
-//
-// We have already introduced the SCALAR token above.  The following tokens are
-// used to describe aliases, anchors, tag, and scalars:
-//
-//      ALIAS(anchor)
-//      ANCHOR(anchor)
-//      TAG(handle,suffix)
-//      SCALAR(value,style)
-//
-// The following series of examples illustrate the usage of these tokens:
-//
-//      1. A recursive sequence:
-//
-//          &A [ *A ]
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          ANCHOR("A")
-//          FLOW-SEQUENCE-START
-//          ALIAS("A")
-//          FLOW-SEQUENCE-END
-//          STREAM-END
-//
-//      2. A tagged scalar:
-//
-//          !!float "3.14"  # A good approximation.
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          TAG("!!","float")
-//          SCALAR("3.14",double-quoted)
-//          STREAM-END
-//
-//      3. Various scalar styles:
-//
-//          --- # Implicit empty plain scalars do not produce tokens.
-//          --- a plain scalar
-//          --- 'a single-quoted scalar'
-//          --- "a double-quoted scalar"
-//          --- |-
-//            a literal scalar
-//          --- >-
-//            a folded
-//            scalar
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          DOCUMENT-START
-//          DOCUMENT-START
-//          SCALAR("a plain scalar",plain)
-//          DOCUMENT-START
-//          SCALAR("a single-quoted scalar",single-quoted)
-//          DOCUMENT-START
-//          SCALAR("a double-quoted scalar",double-quoted)
-//          DOCUMENT-START
-//          SCALAR("a literal scalar",literal)
-//          DOCUMENT-START
-//          SCALAR("a folded scalar",folded)
-//          STREAM-END
-//
-// Now it's time to review collection-related tokens. We will start with
-// flow collections:
-//
-//      FLOW-SEQUENCE-START
-//      FLOW-SEQUENCE-END
-//      FLOW-MAPPING-START
-//      FLOW-MAPPING-END
-//      FLOW-ENTRY
-//      KEY
-//      VALUE
-//
-// The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
-// FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
-// correspondingly.  FLOW-ENTRY represent the ',' indicator.  Finally the
-// indicators '?' and ':', which are used for denoting mapping keys and values,
-// are represented by the KEY and VALUE tokens.
-//
-// The following examples show flow collections:
-//
-//      1. A flow sequence:
-//
-//          [item 1, item 2, item 3]
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          FLOW-SEQUENCE-START
-//          SCALAR("item 1",plain)
-//          FLOW-ENTRY
-//          SCALAR("item 2",plain)
-//          FLOW-ENTRY
-//          SCALAR("item 3",plain)
-//          FLOW-SEQUENCE-END
-//          STREAM-END
-//
-//      2. A flow mapping:
-//
-//          {
-//              a simple key: a value,  # Note that the KEY token is produced.
-//              ? a complex key: another value,
-//          }
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          FLOW-MAPPING-START
-//          KEY
-//          SCALAR("a simple key",plain)
-//          VALUE
-//          SCALAR("a value",plain)
-//          FLOW-ENTRY
-//          KEY
-//          SCALAR("a complex key",plain)
-//          VALUE
-//          SCALAR("another value",plain)
-//          FLOW-ENTRY
-//          FLOW-MAPPING-END
-//          STREAM-END
-//
-// A simple key is a key which is not denoted by the '?' indicator.  Note that
-// the Scanner still produce the KEY token whenever it encounters a simple key.
-//
-// For scanning block collections, the following tokens are used (note that we
-// repeat KEY and VALUE here):
-//
-//      BLOCK-SEQUENCE-START
-//      BLOCK-MAPPING-START
-//      BLOCK-END
-//      BLOCK-ENTRY
-//      KEY
-//      VALUE
-//
-// The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
-// increase that precedes a block collection (cf. the INDENT token in Python).
-// The token BLOCK-END denote indentation decrease that ends a block collection
-// (cf. the DEDENT token in Python).  However YAML has some syntax pecularities
-// that makes detections of these tokens more complex.
-//
-// The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
-// '-', '?', and ':' correspondingly.
-//
-// The following examples show how the tokens BLOCK-SEQUENCE-START,
-// BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner:
-//
-//      1. Block sequences:
-//
-//          - item 1
-//          - item 2
-//          -
-//            - item 3.1
-//            - item 3.2
-//          -
-//            key 1: value 1
-//            key 2: value 2
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          BLOCK-SEQUENCE-START
-//          BLOCK-ENTRY
-//          SCALAR("item 1",plain)
-//          BLOCK-ENTRY
-//          SCALAR("item 2",plain)
-//          BLOCK-ENTRY
-//          BLOCK-SEQUENCE-START
-//          BLOCK-ENTRY
-//          SCALAR("item 3.1",plain)
-//          BLOCK-ENTRY
-//          SCALAR("item 3.2",plain)
-//          BLOCK-END
-//          BLOCK-ENTRY
-//          BLOCK-MAPPING-START
-//          KEY
-//          SCALAR("key 1",plain)
-//          VALUE
-//          SCALAR("value 1",plain)
-//          KEY
-//          SCALAR("key 2",plain)
-//          VALUE
-//          SCALAR("value 2",plain)
-//          BLOCK-END
-//          BLOCK-END
-//          STREAM-END
-//
-//      2. Block mappings:
-//
-//          a simple key: a value   # The KEY token is produced here.
-//          ? a complex key
-//          : another value
-//          a mapping:
-//            key 1: value 1
-//            key 2: value 2
-//          a sequence:
-//            - item 1
-//            - item 2
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          BLOCK-MAPPING-START
-//          KEY
-//          SCALAR("a simple key",plain)
-//          VALUE
-//          SCALAR("a value",plain)
-//          KEY
-//          SCALAR("a complex key",plain)
-//          VALUE
-//          SCALAR("another value",plain)
-//          KEY
-//          SCALAR("a mapping",plain)
-//          BLOCK-MAPPING-START
-//          KEY
-//          SCALAR("key 1",plain)
-//          VALUE
-//          SCALAR("value 1",plain)
-//          KEY
-//          SCALAR("key 2",plain)
-//          VALUE
-//          SCALAR("value 2",plain)
-//          BLOCK-END
-//          KEY
-//          SCALAR("a sequence",plain)
-//          VALUE
-//          BLOCK-SEQUENCE-START
-//          BLOCK-ENTRY
-//          SCALAR("item 1",plain)
-//          BLOCK-ENTRY
-//          SCALAR("item 2",plain)
-//          BLOCK-END
-//          BLOCK-END
-//          STREAM-END
-//
-// YAML does not always require to start a new block collection from a new
-// line.  If the current line contains only '-', '?', and ':' indicators, a new
-// block collection may start at the current line.  The following examples
-// illustrate this case:
-//
-//      1. Collections in a sequence:
-//
-//          - - item 1
-//            - item 2
-//          - key 1: value 1
-//            key 2: value 2
-//          - ? complex key
-//            : complex value
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          BLOCK-SEQUENCE-START
-//          BLOCK-ENTRY
-//          BLOCK-SEQUENCE-START
-//          BLOCK-ENTRY
-//          SCALAR("item 1",plain)
-//          BLOCK-ENTRY
-//          SCALAR("item 2",plain)
-//          BLOCK-END
-//          BLOCK-ENTRY
-//          BLOCK-MAPPING-START
-//          KEY
-//          SCALAR("key 1",plain)
-//          VALUE
-//          SCALAR("value 1",plain)
-//          KEY
-//          SCALAR("key 2",plain)
-//          VALUE
-//          SCALAR("value 2",plain)
-//          BLOCK-END
-//          BLOCK-ENTRY
-//          BLOCK-MAPPING-START
-//          KEY
-//          SCALAR("complex key")
-//          VALUE
-//          SCALAR("complex value")
-//          BLOCK-END
-//          BLOCK-END
-//          STREAM-END
-//
-//      2. Collections in a mapping:
-//
-//          ? a sequence
-//          : - item 1
-//            - item 2
-//          ? a mapping
-//          : key 1: value 1
-//            key 2: value 2
-//
-//      Tokens:
-//
-//          STREAM-START(utf-8)
-//          BLOCK-MAPPING-START
-//          KEY
-//          SCALAR("a sequence",plain)
-//          VALUE
-//          BLOCK-SEQUENCE-START
-//          BLOCK-ENTRY
-//          SCALAR("item 1",plain)
-//          BLOCK-ENTRY
-//          SCALAR("item 2",plain)
-//          BLOCK-END
-//          KEY
-//          SCALAR("a mapping",plain)
-//          VALUE
-//          BLOCK-MAPPING-START
-//          KEY

-//          BLOCK-END
-//          BLOCK-END
-//          STREAM-END
-//
-// YAML also permits non-indented sequences if they are included into a block
-// mapping.  In this case, the token BLOCK-SEQUENCE-START is not produced:
-//
-//      key:
-//      - item 1    # BLOCK-SEQUENCE-START is NOT produced here.
