that is smaller than the size of the Slater-matrix * Removed the Slater-matrix as an argument, since it is not used in the algo. * Added a manual 4x4 example to debug MaponiA3 to work with a number of updates that is smaller than the size of the Slater-matrix * Added a new Octave script to quickly check if the computes inverse is correct.
