/*
* This main contract will be owned by a bookie, which will be in charge of adding the bets. 
* The bets will be "subcontracts" that will selfdestruct at a certain point 
* Utilizes Oracle for data gathering and fulfilling of contract
* Ideally, bets can be placed between two individual addresses, book takes cut.
* Other bets are between book and external user
*
* Got to figure out how to tie this all together when it's DEFI. 
* Do I have a worker checking hourly for closing bets? Where is the worker hosted?
* Where do I store past bets so that my bets that are self destructing are still accesible?
