Script: Workspaces.js
	Save and load workspaces. The Workspaces emulate Adobe Illustrator functionality remembering what windows are open and where they are positioned. There will be two versions, a limited version that saves state to a cookie, and a fully functional version that saves state to a database.

	Function: saveWorkspace
		Save the current workspace.

	Syntax:
	(start code)
		MochaUI.saveWorkspace();
	(end)

	Notes:
		This is experimental. This version saves the ID of each open window to a cookie, and reloads those windows using the functions in mocha-init.js. This requires that each window have a function in mocha-init.js used to open them. Functions must be named the windowID + "Window". So if your window is called mywindow, it needs a function called mywindowWindow in mocha-init.js.
