/**
A simple Solidity smart contract which generates a random number between 0 and the desired max number.
Uses two functions to generate the random number:
- First "prepareRandom" should be called. The function will set the "preparationBlockNumber" to the current block number.
- Second "roll" should be called to generate the number. The function generates a random number using current block difficulty, timestamp, caller address,
 and the blockhash of the block when "prepareRandom" has been called. This way, as the blockhash of the block can't be know before the "prepareRandom" transaction goes thorugh,
 the result of the roll can't be predicted and thus manipulated.

How many times the roll has been called and all the previous results are recorded in the blockchain.
