Since PEAR::DB is entirely a waste of resources if you're just using MySQL, this is a class that
replicates the PEAR API but is much more lightweight, (roughly 1/6 the size).
If you're into keeping up to date, then the PEAR people (or at least someone who is involved
with PEAR I assume) have informed me that PEAR::DB is no longer maintained and for new projects
you should be using MDB2. Ho hum. Personally I'm not into learning new APIs though.
