Base object for JSON -> Python object mapping.
Subclasses of this object will handle their language specific JSON input,
and map that onto this standard Python object.
Subclasses may also include language-specific attributes on this object.
Arguments:
:param obj: JSON object representing this object
:param jinja_env: A template environment for rendering this object
:param url_root: API URL root prefix
Required attributes:
:var str id: A globally unique indentifier for this object.
Generally a fully qualified name, including namespace.
:var str name: A short "display friendly" name for this object.
Optional attributes:
:var str docstring: The documentation for this object
:var list imports: Imports in this object
:var list children: Children of this object
:var list parameters: Parameters to this object
:var list methods: Methods on this object
