Suggested additional text on hook_civicrm_searchTasks

The current description of the $tasks Parameter for the hook_civicrm_searchTasks Hook contains the text:

Class can be an array of classes (not sure what that does :( ).

I suggest this be modified to include explanatory text on the following lines:

Class can also be an array of classes. This is used when the action of the task is carried out in more than one step, by code contained in multiple classes. For example the 'Data Export' action has two steps: a selection of export options performed by (a subclass of) CRM_Export_Form_Select, and a definition of fields to be exported performed by (a subclass of) CRM_Export_Form_Map.

Please edit the above as appropriate.
