Implemented FeatureHandler for an easy-to-use and modular matrix bot. The FeatureHandler manages all commands and the corresponding functions that will be called when a known command is posted to the chat. New commands can be added to the bot by simply calling the add_feature method, which takes the command and the function that will be called for the specified command. The function must take a sender and a message argument. No further restrictions!
