SOLUTION TO KEPLER'S EQUATION
The given data is M = Mean Anomaly, e = eccentricity of orbit, and eps is the
limit of the convergence in Newton's method of iteration. Usually eps = .000001 of
a radian.
When the absolute value of delta E <= .000001, then Kepler's Equation is solved
where E, the eccentric anomaly, is accurate to 6 decimal places.
Remember the range of M is 0 <= M <= 2*pi, where pi = 3.141592654.
