void constants ( double &g, double &c, double &h )

//****************************************************************************80
//
//  Purpose:
//
//    constants() stores, and returns constants "g", "c" and "h".
//
//  Discussion:
//
//    Calling constants(g,c,h) returns the values of g, c, and h.
//
//    Because the values never change, and don't need to be computed,
//    we use assignment statements here, instead of persistent data.

//  Output:
//
//    double &G: gravitational constant m^3/s^2/kg
//
//    double &C: light speed, m/s.
//
//    double &H: Planck's constant, j s;
