Class: Subcommand<PreParseReturn, Options>

The class to extends for commands that have subcommands. Specify the subcommands through the Subcommand.Options.subcommands option.

Note that you should not make all your commands extend this class, only the ones that have subcommands. The reason for this is that this class implements Command.messageRun and Command.chatInputRun which you wouldn't necessarily want to do for commands that don't have subcommands. Furthermore, it also just adds general unnecessary memory overhead.
