[BioC] Odds Ratio in GOstat

[Seth Falcon]

Just a quick update:

Naomi sent me data offlist and I can reproduce the problem with the
count and size.  I'm investigating...

I think it may be related to the ath1121501 annotation package and
differences in how it is structured from other annotation packages.

Clearly that doesn't make a lot of sense.  I'm pretty sure the
hyperGTest code would remove the genes from the test set that are not
in the specified universe.
