    When a function named 'onHotswap' is present in a module,
    this function is called after the module is reloaded.
    This should be used to trigger a redisplay of the screen or
    in general to discard cached results that are to be calculated
    again using the new method definitions.
    If onHotswap is not defined the module is reloaded anyway, but afterwards
    no further actions are performed. In this case the changed code has to be
    activated some other way like minimizing and restoring the window to be
    repainted.
