How it works:
* A random number is hexed and submitted to the contract to begin the round.
* When ETH is sent to the contract, the sender's address and timestamp is written to each ticket the ETH can buy.
* After the time limit is up, the owner submits the non-hexed number to the contract to be verified.
* If verified the number is used as the final variable in selecting a winning ticket, along with variables from tickets selected by their % based position in the list.
* Winner takes all! (less 5% fee)
--------------
* 50% of all fees are paid to a smart contract where EIT investors can collect dividends at any time.
