/*************  INSTRUCTIONS  *************
 Place it into a script right below the config section at the top and it will replace
 the bet/skip function with mock functions which don't interact with the server. 
 
 A few points to note:
 
 1. Latency won't exist with these, and results are returned almost instantly, this
    could cause the browser to freeze up or make the script unobservable unless the
    script includes a sleep or bet delay function. For convenience there's one included
    but disabled by default, just enable the SIM_MODE_SLEEP setting.
