simple non relational index example

[Jak Sprats]

Hi

I wrote up a very simple example of how to use Alchemy DB's non-
relational indexes using redis SETs.

https://gist.github.com/735785 (in bash)

This should illustrate that you can store your data in a Relation
Table in AlchemyDB and then have specialised indexes (redis SET or
ZSET) using redis objects, and Querying the Relational table using
SetIntersection or SetUnion is trivial

p.s. AlchemyDB is currently being heavily tested and should be
production ready by the end of the month, which means I have been
using various tools to make sure AlchemyDB is bug-free :)
