Update algorithm to use TLE mean elements as first guess, with mean anomaly derived from osculating true anomaly at departure (not converging).
Update algorithm so that TLE epoch is not changed (not converging).
Reduce solver tolerance (converging for 0-maneuver case.
Rewrite algorithm from scratch (part 1).
Update algorithm and set up clean conversion function (not yet converging).
Clean up code, add Doxygen comments, add local D2D functions library.
