Made the logic and comments much clearer about how to reshape, expand axis, and tile numpy arrays.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Restored profiling script to normal.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Needed to increase the relative tolerance when testing if pA array is 1.

Now system test Relax_disp.test_hansen_cpmg_data_missing_auto_analysis passes.

Also added some comments lines, to prepare for mask replace of values.
For example if only some of etapos values should be replaced.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Very important fix, for only replacing part of data array which have Nan values.

Before, all values were replaced, which was wrong.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Fixed that arrays are correctly initiated with one or zero values.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Small edit to profiling script, to help bug finding.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Made the back_calc array be initiated as copy of the values array.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Reordered arrays for beauty of code.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Removed all looping over spin and spectrometer frequency.

This is the last loop!
Wuhu.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Removed dw_frq_a numpy array, as it was not necessary.
