Changes:

Added two new database field types:  datetime.date and  
datetime.datetime.  They are stored as strings, but are input and output 
as instances of datetime.date and datetime.datetime respectively.   You 
can use them just like any other field:  you can use them as selection 
criteria (i.e. db.select('plane.tbl', ['began_service'], ['>=%s' % 
datetime.date(1937,12,31)) or use them to specify the sort order of the 
result set of a select statement (i.e.  db.select('plane.tbl', ['name'], 
['.*'], sortField='range', ascending=False)).

Made a few internal optimizations when running queries that have  
resulted in a 15-20% speed increase when doing large queries or updates.

Changed the name of all private methods from starting with two 
underscores to starting with one underscore based on a discussion in 
comp.lang.python as to how to properly name private variables.
