/**********************************************************************
Audacity: A Digital Audio Editor
Project.h
Dominic Mazzoni
In Audacity, the main window you work in is called a project.
Projects 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).
