Switch on polarisation for montecarlo radiative transfer solver. By default uses unpolarized sunlight (light starting with an initial Stokes Vector (1,0,0,0). Optionally users may provide one of the following numbers to specify one of the following initial Stokes vectors:
Details about the implementation of polarisation are described in (Emde et al., 2010).
