a large chunk.  This patch adds a general SolrDocument interface and includes a concrete implementation

 This is required for the INCREMENT command and useful for modifying documents.  SolrDocument
is also generally useful for SOLR-20

> The one (potentially) controversial part is that I added a function to FieldType:
>  public Object toExternalValue(Fieldable f);
> This asks each field type to convert its Fieldable into its real type, for example
>  public Integer toExternalValue(Fieldable f) {
>    return Integer.valueOf( toExternal(f) );
>  }
> By default, it returns a string value.  If this addition is too much, there are other
(less clean) ways to handle the INCREMENT command.  My real motivation for this addition is
that it makes it possible to implement an embeddable SOLR-20 client that does not need an
HTTP connection.

> The SimpleSolrDoc implementation was written for SOLR-20.  It needs to play nice with
EL, so it implements a few extra map function that may not seem necessary:
>  ${doc.values['name']]} gets a collection
>  ${doc.valueMap['name']]} gets a single value for the field
> - - - -
> The tests cover all "toExternalValue" changes in schema.*  
> SimpleSolrDoc and DocumentBuilder have 100% test coverage.
