    A toonz project is identified by a project name that matches a folder with the same name in the project root.\n
	The project folder can contains saveral other folders. 
	By default, five folders are created: Inputs, Drawings, Scenes, Extras and Outputs. 
	Each of this folders can be renamed using the setFolder(string name, TFilePath path) method.
	Usually, the \b name parameter is choosen from inputs, drawings, scenes, extras and outputs;
	the \b path parameter contains the folder that can have a different name from them.
	All association between names and folder are kept in a mapping.\n
	A folder of a project can be constant or scene dependent. A constant folder is used by 
	every scene created in the project to save or load data. A scene dependent folder is used only by the scene 
	from wich the folder depends. A scene dependent folder contains the string "$scene" in its path. 

	\code
	e.g. 
	Scene path: "...\\prodA\\episode1\\scenes\\sceneA.tzn"
	Drawings scene dependent folder: "...\\prodA\\episode1\\$scene\\drawings"
	Drawings folder path: "...\\prodA\\episode1\\SceneA\\drawings"
