 * @class GSource
 *
 * @brief Class that handles gamma-ray sources
 *
 * The GSource class stores the physical attributes of a gamma-ray source,
 * which is the distribution of photon arrival directions in form of a
 * spatial source model, the photon energy, and the photon arrival time.
 * The class is very similar to the GPhoton class, yet instead of a given
 * photon arrival direction it contains a spatial model pointer. Note that
 * the class does not allocate or deallocate the spatial model pointer,
 * it just is a carrier of a pointer which is handled outside the class.
 *
 * Each source also has a name so that it can be identified.
