This is a wrapper around the sqlite3.Connection objct that adds some
nice functionality to make working with SQL easier.
I defined the following magic methods:
* __enter__() to manually begin a transaction
* __exit__() to commit or rollback a manual transaction
* __call__() to execute a SQL statement with either positional or
keyword arguments.
Additionally:
* I define a "CASEFOLD" function that can be used in queries
to lowercase unicode text when searching.
* I set foreign_keys = ON so foreign keys checking is always enabled
* I provide an executemany() function for running running the same
statement multiple times with different arguments.
