Model: Librat

Phase: RAMI IV

The librat model is the 'forward' version of the drat model, that is, within librat the rays are traced from the source to the viewer. librat features the same capabilities as the drat model.

The model is now written as a stand-alone library now, so the core function calls can be incorporated into any code quickly and easily.
