Add a simple glfps program

This simply calls out to the glaze program with an appropriate path to
the wrapper library, (assuming the wrapper library lives next to the
glfps program). If this glfps program were to be installed somewhere,
it should be updated to reflect the path to which libglfps is also
installed.
