ResultSpec behavior incorrect in several cases

                 Key: UIMA-1860
                 URL: https://issues.apache.org/jira/browse/UIMA-1860
             Project: UIMA
          Issue Type: Bug
          Components: Core Java Framework
            Reporter: Marshall Schor
            Assignee: Marshall Schor
             Fix For: 2.3.1


Write more test cases examining behavior regarding type/subtype inheritance for 
both features and types in result specs, and language subsumption testing, 
using both containsType or containsFeature, with and without intersection.

Issues found include:

* Supertype with allFeatures sets allFeatures for all subtypes.  Correct 
behavior: specifying allFeatures on a type should only imply allFeatures that 
are known for that type.  Features introduced only in subtypes should not be 
included.

* Serialization/deserialization ignores languages other than x-unspecified; it 
should support the full result-specification.  potential (future?) use case: 
sending result specs to remote delegates.

* Assume a feature F introduced in a supertype T.  A result spec T:F should be 
sufficient to return true for a test of T2:F, where T2 is a subtype ot T 
(currently returns false).
