/**********************************************************************
Audacity: A Digital Audio Editor
Project.cpp
Dominic Mazzoni
Vaughan Johnson
*******************************************************************//**
\file Project.cpp
\brief Implements AudacityProject, DropTarget, and FileObject.
Includes Menus.cpp.
*//****************************************************************//**
\class AudacityProject
\brief AudacityProject provides the main window, with tools and
tracks contained within it.
In Audacity, the main window you work in is called a project.
AudacityProjects can contain an arbitrary number of tracks of many
different types, but if a project contains just one or two
tracks then it can be saved in standard formats like WAV or AIFF.
This window is the one that contains the menu bar (except on
the Mac).
\attention The menu functions for AudacityProject, those for creating
the menu bars and acting on clicks, are found in file Menus.cpp
*//****************************************************************//**
\class DropTarget
\brief DropTarget, derived from wxFileDropTarget gives drag and drop
functionality for audio files.
*//****************************************************************//**
\class FileObject
\brief FileObject, derived from wxFileDataObject gives extended drag
and drop functionality for audio files.
*//****************************************************************//**
\class ViewInfo
\brief ViewInfo is used mainly to hold the zooming, selection and
scroll information. It also has some status flags.
