This module brings Django Signals into Evennia. These are events that can be subscribed to by importing a given Signal and using the following code.
When other code calls THIS_SIGNAL.send(sender, **kwargs), the callback will be triggered.
Callbacks must be in the following format:
def my_callback(sender, **kwargs): ...
This is used on top of hooks to make certain features easier to add to contribs without necessitating a full takeover of hooks that may be in high demand.
