// 			- list features
// 			- list actions

//
// XXX the main functionality:
// 		- make previews
// 		- make index
// 		- merge
// 		- clone

// XXX a different approach to this would be an "external" cli controller
// 		script that would contain only cli code and load the ImageGrid
// 		only in the handler...
// 			+ would be allot faster to load.
// 			+ more flexible as we can load more than one instance...
// 		This could still be done via features, just load the cli feature
// 		alone at first and then either create new instances or setup 
// 		additional features as needed...
