Mix-in to add/call inheritable triggers

 Class::Trigger is a mixin class to add and call triggers (hooks)
 that get called at points you specify in your class.
 Class:Trigger allows you to specify an arbitrary number of subroutines
 that are triggered every time something happens in your code, e.g. updating
 a full text search index after INSERT/UPDATE/DELETE queries.
