Another fix for bug #22505 (https://gna.org/bugs/?22505).

This is the failure of the structure.create_diff_tensor_pdb user function when no structural data is
present. Now the cdp.structure data structure is checked, when present, if it contains any data
using its own empty() method.

Created the Structure.test_create_diff_tensor_pdb2 system test.

This is to catch another situation leading to bug #22505 (https://gna.org/bugs/?22505), the failure
of the structure.create_diff_tensor_pdb user function when no structural data is present.

Fix for bug #22505 (https://gna.org/bugs/?22505).

This is the failure of the structure.create_diff_tensor_pdb user function when no structural data is
present. The solution was simple - the CoM of the representation is set to the origin when no
structural data is present, and the check for the presence of data removed.

Fix for the return_r2eff_arrays() dispersion function for exponential curves.

This is a partial solution for bug #22461 (https://gna.org/bugs/?22461).

For the Relax_disp.test_r1rho_kjaergaard_missing_r1 system test, there are multiple relaxation times
for each data set. For example, printing out the exp_type, frq, offset, point, ei, mi, oi, di, and
relax_times data gives:

- R1rho 799777399.1 118.078 431.0 0 0 0 0 [0.0, 0.04, 0.1, 0.2]
- R1rho 799777399.1 118.078 651.2 0 0 0 1 [0.0, 0.04, 0.1, 0.2, 0.4]

Instead of taking the first relaxation time of 0.0, now the maximum time is taken.

Inserted intermediate systemtest, to profile R2eff calculation for R1rho.

Systemtest is: Relax_disp.test_bug_9999_slow_r1rho_r2eff_error_with_mc

This systemtest actually fails, if one tries to do a Grid Search.

This is related to the R2eff values stored as dictionary, and
pipe_control.minimise.grid_setup() will fail.

The function 'isNaN(values[i])' cannot handle dictionary.

Modified intermediate systemtest:
Relax_disp.test_bug_9999_slow_r1rho_r2eff_error_with_mc

to see if the initial Grid Search for 'i0' and 'R2eff' estimation can be skipped.

This is done by converting the exponential curve, to a linear curve, and calculate
the best parameters by a line of best fit by least squares.

This seems like a promising method as an initial estimator of 'i0' and 'r2eff'.

For 500 to 2000 Monte-Carlo simulations, this could have an influence on the timings,
as all grid searchs could be skipped.
