           Summary: add features to support semantic incompatiblity
           Product: Kepler

System should check for semantic compatibility between ports:
1) either automatically
2) or upon user request to check for semantic compatibility

Visually indicate when ports don't match semantically:
1) at run time of a workflow
2) when two semantically incompatible ports are connected
3) or when user has indicated they are now ready for semantic compatibility to 
be checked

Visually indicate and warn user when they attempt to run a workflow that 
contains semantically incompatible components but allow them to go ahead and 
run the workflow if so desired.

Visual indications for structural incompatibility and semantic compatability 
will be different.

Upon discovery of semantic incompatibility, provide access to annnotation 
dialog so user can adjust annotations of components if so desired.

There are three possibilities when checking for semantic compatibility:
1) semantically valid because ports are annotated
2) semantically invalid because ports are annotated and don't match
3) don't know semantics because ports are not annotated (unobstrusive)

Consider some visual indication of a workflow icon if it contains semantically 
incompatible components.
