*What's New*

Well, in the spirit of "Release early and often", here's a new version.
This one has some bug fixes and code cleanup, but the big news is I
implemented a new index initialization routine that has cut index
initialization time in half, greatly improved performance on some
queries, and reduced memory consumption by one-third in some circumstances.

Here's a totally non-scientific example. Doing a range query (Time data
type) against an 80,000 record table and returning a 5,000 record result
set:

Version: 0.1.1
-------------------
Index initialization: 2 seconds
Query time: 0.75 seconds

Version: 0.1.0
-------------------
Index initialization: 5.5 seconds
Query time: 1 .8 seconds

By the way, here's how KirbyBase performed doing the same query:

KirbyBase: 2.6
-------------------
Index initialization: 12 seconds
Query time: 20 seconds

Not bad for a young mongoose!


*What is Mongoose?*

Mongoose is a database management system written in Ruby. It has an
ActiveRecord-like interface, uses Skiplists for its indexing, and
Marshal for its data serialization. I named it Mongoose, because, like
Rudyard Kipling's Rikki-Tikki-Tavi, my aim is for it to be small, quick,
and friendly.
