Log Message:
Implemented the first three items of the 'peak.model' refactoring plan;
feature metadata, 'model.Immutable' hash-and-compare support, and
immutables requiring all features to be read-only.  (The latter required
some changes to some 'model.DataType' subclasses in various PEAK modules.)
Added tests for some of the metadata and the immutable read-only check, but
no tests yet for immutable objects' hash-and-compare support.
