#2 de-serializer and json-rpc-java compatibility

[Arthur Blake]

Would be nice if there was a de-serializer too. Flexjson would be most immediately useful to me (and I think a lot of other people too) if I could drop in the flexjson serializer (and missing deserializer) for use in an existing json-rpc-java project as an alernative "codec".
For this to really work right, it would have to be able to use the "class-hinting" and "type-mapping" scheme in use there. See http://oss.metaparadigm.com/jsonrpc-1.0/manual.html#type-mapping
