=head1 NAME

Kephra::API::EventTable - API to internal events

=head1 DESCRIPTION

Every routine can subscribe a callback to any event that will than triggered
when that event takes place. Also extentions (plugins) can do that. 
Event ID can also be triggered to simulate application events. 
Some function do freeze events to speed up certain repeating actions 
(don't forget to thaw after that). Callbacks can also sanely removed,
if no longer needed.

Names of Events contain dots as separator of of namespaces.
