#2 Database backend

[R Midwinter]

A database backend would be nice to store the generated
iris profiles in. There would need to be a interface
from the Java code for adding and removing iris
profiles and searching for matches.

HSQLDB would probably be suitable, particularly as this
perhaps is an application we only want to be local.

Some thought needs putting to hamming distance matching
and how it'll link with the database in terms of
performance particularly.
