Paul Licameli 5e7d41ec07 Each .cpp/.mm file includes corresponding header before any other...
... except Audacity.h

This forces us to make each header contain all forward declarations or nested
headers that it requires, rather than depend on context.

Audacity: A Digital Audio Editor

********************************************************************//**
\class FileNames
\brief Provides Static functions to yield filenames.
This class helps us with setting a base path, and makes it easier
for us to keep track of the different kinds of files we read and write
from.
JKC: In time I plan to add all file names and file extensions
used throughout Audacity into this one place.
