/**
    Due to the imperfect design of the buttons, a press on the button is registered multple times.
    The debouncer module makes sure that these false positives of the button are going to be ignored.
    
    Also, this module provides a multiclick service which allows the user to press the button multiple times 
    within a certain time frame. Therefore, multiple actions can be mapped to a single button.
