"cgr2_2 contains the last Conjgugate Transpose and the last explicit matrix inversion" -> preliminary refactoring
requested to merge 29-cgr2_2-contains-the-last-conjgugate-transpose-and-the-last-explicit-matrix-inversion into master
Until now, I have only done some refactoring and wrote tests. Since this does not affect any numerical properties I propose to merge the current state with the master. The branch should still exist after this change.
