Simple test script for timing GenBank parsing

I've attached a trivial script to time parsing all the GenBank files in 
directory to help anyone wanting to benchmark this change.

Further testing with Python 2.5 on Linux, this time also with some large
Eurakyotics files, appears to confirm a very large speed up (most obvious on
feature rich GenBank files of course).

I still want to check this on other versions of python...
