+// On connection setup, the client sends six bytes of preamble -- a four
+// byte magic, a byte of version, and a byte of authentication type.
+//
+// We then send a "ConnectionHeader" protobuf of user information and the
+// 'protocol' or 'service' that is to be run over this connection as well as
+// info such as codecs and compression to use when we send cell blocks(see below).
+// This connection header protobuf is prefaced by an int that holds the length
+// of this connection header (this is NOT a varint).  The pb connection header
+// is sent with Message#writeTo.  The server throws an exception if it doesn't
+// like what it was sent noting what it is objecting too.  Otherwise, the server
+// says nothing and is open for business.

+// <Optionally a Cell block>

+// in the RequestHeader expects; e.g. if the method is a scan, then the pb
+// Request Message is a GetRequest, or a ScanRequest.  A block of Cells
+// optionally follows.  The presence of a Request param Message and/or a
+// block of Cells will be noted in the RequestHeader.
+//
+// Response is the mirror of the request:
+//
+// <An int with the total length of the response>

+// <Optionally a Response Result Message written out using Message#writeDelimitedTo>
+// <Optionally a Cell block>

+// ...where the Response Message is the response type that goes with the
+// method specified when making the request and the follow on Cell blocks may
+// or may not be there -- read the response header to find out if one following.
+// If an exception, it will be included inside the Response Header.
+//
+// Any time we write a pb, we do it with Message#writeDelimitedTo EXCEPT when
