[Biopython] SQL Alchemy based BioSQL

[Kyle Ellrott]

I've posted a git fork of biopython with a BioSQL system based on SQL
Alchemy.  It can be found at git://github.com/kellrott/biopython.git
It successfully completes unit tests copied from test_BioSQL and
test_BioSQL_SeqIO.
The unit testing runs on sqlite.  But it should abstract out to any
database system that SQLAlchemy supports.  From the web site, the list
includes: SQLite, Postgres, MySQL, Oracle, MS-SQL, Firebird, MaxDB, MS
Access, Sybase, Informix, and IBM DB2.
