newPrivateKey: Creates a new Wallet inside the class instance. Always returns true.getPrivateKey: Returns the WIF for this Wallet.loadPrivateKey: Takes in a WIF string and loads it into this class instance. Returns true on success and false on failure.getAddress: Returns the address for this Wallet.newTX: Returns a hex serialized transaction to be broadcasted on the PIVX mainnet. The first argument is an array of arrays. Each child array has a string of the TX hash to spend, an int of the output we're spending, and a string of how much it's worth. The second argument is a string of the destination address. The third is a string of the amount to send. The fourth is a string of the fee to pay (not per k/b). All quantities are denoted in Satoshi.
