Re-inserted safety checks in lin/dispersion/cr72.py file.

This is re-inserted for the rank_1 cases.

This makes the unit-tests pass again.

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

Fix for calculation of the larmor frequency per spin in profiling script.

The frq loop should also be up-shifted.
It was now extracted as 0.0.

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

In profiling script, moved up the calculation of values one level.

This is to better see the output of the profiling iterations for cr72.py.

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

Removing looping over exp and offset indicies in calc_chi2. They are always 0 anyway.

This brings a little speed.

Modified profiling script to calculate correct values when setting up R2eff values.

This is to test, that the return of chi2 gets zero.

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

Moved the creation of special numpy structures outside target function.

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

Added print out of chi2 to profile script.

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

Altered profiling script to report cumulative timings and save to temporary files.

Temporary changed the lib/dispersion/cr72.py function to unsafe state.

This change turns-off all the safety measures, since they have to be re-implemented
for higher dimensional structures.

Initial try to alter the target function calc_CR72_chi2.

This is the first test to restructure the arrays, to allow for higher dimensional computation.
All numpy arrays have to have same shape to allow to multiply together.
The dimensions should be [ei][si][mi][oi][di]. [Experiment][spins][spec. frq][offset][disp points].
This is complicated with number of disp point can change per spectrometer frequency.

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

This implementation brings a high overhead.
The first test shows no winning of time.
The creation of arrays takes all the time.
