[DAS2] Modifying com.affymetrix.igb.das2 classes

[Helt,Gregg]

Brian and Marc, 
 
I'm about to start seriously modifying the IGB DAS/2 classes in the
com.affymetrix.igb.das2 package.  There's code in there you wrote to
work with materials, assays, results, and ontology.  I think we
discussed at some point splitting this stuff out into a separate
package(s).  Which sounds good, especially since (as I understand it),
these domains are separate from the DAS/2 "sequence" domain.  The only
place there's a lot of mixture of code for these domains with the
sequence parts is in Das2VersionedSource.  Is it okay if I move this out
(or comment it out) of Das2VersionedSource while I renovate other parts
of the class?
 
            thanks,
            Gregg
