This Source DLL models an Hermite-Gaussian Source using ray generated at position and angles following the intensity of the electric field and the angular spectrum. 

This Source DLL is inspired by the known DLL (Source): Non-sequential Astigmatic Gaussian

DLL (Source): Hermite-Gauss take 4 parameters:

• w0_x, w0_y are the theoretical beam waist of the fundamental mode
• n_x, m_y are the mode indices in the corresponding directions
