 * @class PhotosDebugRandom
 *
 * @brief Random generator for debugging purposes
 *
 * Random generator with ability to save and restore state, set custom
 * state and print current state. This class extends PhotosRandom class.
 * PhotosRandom is a static class, therefore this extension works
 * automatically for FORTRAN code without any changes.
 * Our random generator is the C++ follow-up of FORTRAN generator by 
 * F. James DD-Report, November 1988. and  G. Marsaglia and A. Zaman,  
 * FSU-SCR-87-50,
