The Raysect optical package.

This package builds upon the Raysect core to provide a framework for geometric
optical simulations.

Units
-----

Unless otherwise stated, the following units are used throughout the optical
framework:

 dimensions are in meters (m)
 wavelength is in nanometers (nm)
 energy is in Joules (J)
 power is in Watts (W)
 solid angle is in steradians (str)
 radiance is in W/m^2/str
 spectral radiance is in W/m^2/str/nm
