/*
This is the type of cell used throughout the appkit, in file viewers and the like, to display an icon with an associated title. The nomal use is for the icon to represent an object. If given a delegate, the icon cell treats that delegate as the object it should display and sends it query messages to determine its title, icon, and dragging characteristics.
In conjuction with the IKIconPath class, IKCells support drag-and-drop, acting as both sources and destinations. The title of an editable IKCell can be changed by clicking on the title region and typing a new one. The delegate is kept informed throughout dragging and editing so that it can initiate appropriate changes throughout the application.

Instances maintain their own flag to indicate whether they are editable so that the IKIconPath can reuse a few matrix methods without the matrix class getting confused.
