    This is the base class for commands. In order to load a command a few conditions must be met:
    1) The class name MUST begin with 'Command' i.e. CommandTTS, CommandBan, etc...
    2) the class MUST extend AbstractCommand

    Generally, it would be advisable to define the command (something like !so, !tts, !songrequest) as a variable of the
    class and to then call super().__init__(command)
