+Abstract Object Encoder/Decoder
+
+Classes used to define Datatypes using an abstract syntax, and
+encode/decode instances of those types using a concrete message format.
+
+Datatypes are specified in JSON Abstract Syntax Notation (JASN) schemas,
+or Python classes, or "Pseudo ASN" documemnts, all of which represent and can
+be generated from the same abstract schema.
+
+Currently supports three JSON-based concrete message formats (verbose, concise,
+and minimized) but can be extended to support XML-based and binary formats.
