[BioSQL-l] crc for sequences

[Hilmar Lapp]

I added a column CRC to biosequence in our Oracle version which I'll 
soon propagate to the repository. This column is meant to hold a CRC 
for the sequence, which - if indexed - can be very handy to lookup 
perfect matches to a query sequence, and also to find fully redundant 
sequences.

This column is supported by bioperl-db as an optional column that can 
be enabled/disabled by commenting/uncommenting a single line in the 
object-relational definition in BaseDriver.pm.

If added to the mysql/Pg versions of the schema, it would be an 
optional column (nullable) and therefore backwardly compatible as well 
as compatible with other bio* bindings unless any of those bindings did 
a SELECT * FROM biosequence WHERE blah.

Any comments or objections to me adding this column to the mysql/Pg 
versions as well?
