 FSB Example
 Copyright (c), Firelight Technologies Pty, Ltd 2004-2016.

 This example demonstrates the usage of the FSB format, generated by the FSBank tool.
 It is simply a packed file format, with sounds contained within.  This is a cross platform
 format that is useful to keep the data format optimal for the platform you are targeting.
 (ie PS2, Xbox, Gamecube have native compression formats)
