* Modified Maponi algo 3 so that it can be used with a number of updates
...
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.

Added QMCChem test dataset with 3 updates. Renamed files, added the Fortran program QMCChem_dataset_test.f90 to start testing the QMCChem dataset. Wrote and tested Fortran code to import the test dataset.

Calling C++ function MaponiA3 from Fortran

The Fortran interface to C++ fuction MaponiA3() works but the mechanism of passing the 2D arrays from Fortran to C++ must be improved. Now the passed 'linear' 2D arrays are copied and reshaped into usable 2D arrays. This needs to be replaced with some suitable casting mechanism.

Prepared the example matrix of Example 8 of the paper and its

decomposition in the Fortran code and made a basic call to the
subroutine MYSUBROUTINE, which is bound to the C++ void function
'Sherman-Morrison();. For now compilation fails with lots of undefined
references.'

Fix/upd inverse

Update of A0_inv fixed. matMul(...) breaks link between A0_inv and Slater_inv. Fixed by creating a new pointer that points to where Slater_inv points to before it gets reassigned by matMul(...) and then copy the updated elements back to the passed array pointed to by the new pointer.

Split the program in a header file and an implementation file and included them in main. Does not compile. Get the following error: ld: /tmp/icpcnmVxvw.o: in function void showMatrix<int>(int**, unsigned int, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)'

Extracted the SM algorithm and wrote it as a void function that updates the passed old inverse. Does not work yet. For some reason the changes in the inverse do not persist when the function is finished. Also the inverse is not correct.
