/**
* The Java SQL framework allows for multiple database drivers. Each driver should supply a class that implements the Driver interface
*
*
* The DriverManager will try to load as many drivers as it can find and then for any given connection request, it will ask each driver in turn to try to
* connect to the target URL.
*
*
* It is strongly recommended that each Driver class should be small and standalone so that the Driver class can be loaded and queried without bringing in vast
* quantities of supporting code.
*
*
* When a Driver class is loaded, it should create an instance of itself and register it with the DriverManager. This means that a user can load and register a
* driver by doing Class.forName("foo.bah.Driver")
