[Biopython] Record count in pcassay database

That count looks right to me if I manually browse the PubChem
BioAssay database:

http://www.ncbi.nlm.nih.gov/pcassay?term=all[filt]

It looks like you are retrieving the top level assay records. The
counts for total compounds assayed will be much higher but you would
need to examine individual records of interest to determine those.

Hope this helps,
Brad
