/*! \class TProject tproject.h

        \brief Define and handle a toonz project.

    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"

        \endcode

        \n\n

        By default, from the toonz installation, exist allways a toonz project

   called "sandbox".

        \see TProjectManager, TSceneProperties.

/*! \class TProjectManager tproject.h

        \brief Manages all toonz projects. The class provides all needed method

   to retrieve projects paths, names

        and folders.

        It is possible to handle more than one project root.

        The class mantains a container this purpose. All the projects roots must

   be setted by hand in the windows

        registery. By default, only one project root is created when toonz is

   installed.\n

        The project root container can be updated using addProjectsRoot(const

   TFilePath &root), addDefaultProjectsRoot()

        methods.

        The class mantains also information about the current project. The class

   provides all needed method to retrieve

        the current project path, name and folder.
