********************************************************************//**
\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.
