*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.
