/**
* Declare triggers (events) for users to assign actions to.
*
* This hook is used by the trigger module to create a list of triggers (events)
* that users can assign actions to. Your module is responsible for detecting
* that the events have occurred, calling trigger_get_assigned_actions() to find
* out which actions the user has associated with your trigger, and then calling
* actions_do() to fire off the actions.
*
* @return
* A nested associative array.
* - The outermost key is the name of the module that is defining the triggers.
* This will be used to create a local task (tab) in the trigger module's
* user interface. A contrib module may supply a trigger for a core module by
* giving the core module's name as the key. For example, you could use the
* 'node' key to add a node-related trigger.
* - Within each module, each individual trigger is keyed by a hook name
* describing the particular trigger (this is not visible to the user, but
* can be used by your module for identification).
* - Each trigger is described by an associative array. Currently, the only
* key-value pair is 'label', which contains a translated human-readable
* description of the triggering event.
* For example, the trigger set for the 'node' module has 'node' as the
* outermost key and defines triggers for 'node_insert', 'node_update',
* 'node_delete' etc. that fire when a node is saved, updated, etc.
*
