Tests the functionalities on top of KS calculations

The command <tt>make check</tt> performs the series of tests:
- @b BigDFT2Wannier
- @b GEOPT-BFGS
- @b GEOPT-LBFGS
- @b GEOPT-newIG
- @b H2-freq:       Computes the vibration properties of the H2 molecule using finite differences
                    (test the 'frequencies' program).
- @b C6H6-freq:     Tests the possible frozen atom options and calculate the corresponding frequencies
                    This test is not physically relevant.
- @b H2O-slab:      Tests the calculation of the dipolar surfaces.
- @b IO-wf          Input/Output wavefunctions
- @b IO-wf-ETSF     Tests IO with ETSF-IO library
- @b MH_taskgroups  Tests the use of taskgroups
- @b MINHOP         Example to use the minima hopping method.
                    The input Files are:
                    - @b CPUlimit:   CPUlimit in hours
                    - @b earr.dat:   First line,  # of minima found and # of minima to be found
                                   Second line, Eref  (Reference energy) stop if less than that
                                   Third line,  accur Accuracy for rounding
                    - @b input.dat   Used for the first optimization of geometry
                    - @b ioput       First line, Ediff (Difference energy) to reject minima or not if > Ediff
                    - @b poscur.xyz  Initial and current position
                    - @b rand.inp    Seed of random number
- @b NEB            Run Nudged-Elastic Band calculations
- @b NH3            Shows the DIIS geometry relaxation to obtain saddle points
- @b SPLSAD         Spline Saddle Search test
- @b testforces
- @b Xabsb2B        Tests XANES calculations
- @b XabsCG         Tests XANES calculations
- @b XabsCheb       Tests XANES calculations
- @b XabsLanc       Tests XANES calculations
