Motion4D-library extended

Abstract
The new version of the Motion4D library is mainly an update to work with the four-dimensional ray tracing code GeoViS which makes full use of all the implemented metrics and geodesic integrators.

Title of program: Motion4D-library
Catalogue Id: AEEX_v3_1

Nature of problem
Solve geodesic equation, parallel and Fermi-Walker transport in four-dimensional Lorentzian spacetimes. Determine gravitational lensing by integration of Jacobi equation and parallel transport of Sachs basis.
