[BioC] hyperGTest

[Naomi Altman]

Specifically the change that I want to make is to allow duplicates.

We are using novel species.  Several genes from our species may hit 
the same gene from the closest model species due to duplication 
events since diversion.  So, I need to allow duplicates in both the 
universe and the test set.  I'll play with the code a bit - using 
weights might be the simplest.
