Created the numpy array self.index target function which contains index to store the data.

This is for situations where numpy version is under 1.8.

Created function to create the helper index numpy array, to help figuring out the indices to store in the exchange data matrix.

This is for striding through data and store the data correct in the data matrix.

This is for a special situation where numpy version is < 1.8, and where the numpy.linalg.eig() function can only
be performed on square matrices, and not on higher dimensional data.

For this situation, it is necessary to stride through the data.

Implemented second try to stride through data, when computing the eig() of higher dimensional data.
This of data of form: NS, NM, NO, ND, Row, Col.

Systemtest test_sprangers_data_to_ns_mmq_2site survived this transformation.

The systemtest will go from about 2 seconds to 4 seconds.

Implemented first try to stride through data, when computing the eig() of higher dimensional data.

Systemtest test_cpmg_synthetic_b14_to_ns3d_cluster survived this transformation.

The systemtest will go from about 11 seconds to 22 seconds.

Changed graphs after new minimisation algorithm has been implemented.

The values are now slightly different.

Fix for systemtest Relax_disp.test_kteilum_fmpoulsen_makke_check_graphs where minimise has been extended with execute.

Fix for bug #22411 (https://gna.org/bugs/?22411), the failure in loading a Bruker DC T1 data file.

The problem was that there was an empty line with spaces. The logic for skipping empty lines could
not handle lines with just whitespace. This has now been fixed.

Created the Bruker.test_bug_22411_T1_read_fail system test.

This is to catch bug #22411 (https://gna.org/bugs/?22411) as reported by Olena Dobrovolska.

Removed empty directories, which was not used.

Deletion of the r1rho_plotting branch as it has been merged back to trunk.
