Class Editor

The main entry point into the Ace functionality.

The Editor manages the [[EditSession]] (which manages [[Document]]s), as well as the [[VirtualRenderer]], which draws everything to the screen.

Event sessions dealing with the mouse and keyboard are bubbled up from Document to the Editor, which decides what to do with them.
