/**
 * 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.
 *
