/* ==========================================================

Notes:

Previously code handled multiple instances in a single console application

Now have changed it to do a single instance only. With minimal code changes...(i.e. kept [instance] index but it is always 0.

Windows application should call instance_init() once and then in the "main loop" call instance_run().
