/**
* RandomLedger is the main public interface for a random number ledger.
*
* The ledger feature embraces the blockchain capablities,
* leveaged by the Event logs generated by Ethereum Smart Contracts.
* "Events are inheritable members of contracts. When they are called,
* they cause the arguments to be stored in the transaction's log
* - a special data structure in the blockchain. These logs are associated with
* the address of the contract and will be incorporated into the blockchain and
* stay there as long as a block is accessible (forever as of Frontier
* and Homestead, but this might change with Serenity)."
* ++ Read more in the solidity#events documentation. ++
*
* To make a request:
* Step 1: Call requestNumber with the `cost` as the value
* Step 2: Wait waitTime in blocks past the block which mines transaction for requestNumber
* Step 3: Call revealNumber to generate the number, and make it publicly accessable in the UI.
* this is required to create the Events which generate the Ledger.

Hype Inu ($Hype)
HypeINU Token (ERC20) has been created by a team of marketing professionals, designers and game developers. We’ve worked together on different projects for some time and always wondered what the net result would be if we dedicated our time, skills and combined experience towards our own token? So, when better time than #hypeseason?
