update usage comment
AES: string based 'ashex' parameter replaced by integer based 'asnum' parameter for decrypt(); AES-basic: introduction of separate layer to split into blocks for encryption and decryption; AES-basic: separate class instances for encryption and decryption, to stress the point that it'll be different objects, and as a passive test case for the implementation, and key expansion, respectively
