Modified Copyright notice in files to reflect svn log.

The relaxation dispersion auto-analysis now creates the chi2.out text file.

This is for more easily comparing the chi-squared values between analyses.

Editing of the dispersion GUI analysis tutorial in the manual.

The whole section has been proofed and improved.

Renamed system test.

Regarding bug #21344, (https://gna.org/bugs/index.php?21344) - Handling of in sparse acquired R1rho dataset with missing combinations of time and spin-lock field strengths.

The previous test name was rubbish.

Added unit test for loop_time() for r1rho setup.

Regarding bug #21344, (https://gna.org/bugs/index.php?21344) - Handling of in sparse acquired R1rho dataset with missing combinations of time and spin-lock field strengths.

Fixes for the Grace kex plot for the tutorial for dispersion GUI analysis.

The values for the Grace plot were not correct.

Added unit test for count_relax_times() for and R1rho setup.

Regarding bug #21344, (https://gna.org/bugs/index.php?21344) - Handling of in sparse acquired R1rho dataset with missing combinations of time and spin-lock field strengths.

Renamed previous disp_data unit tests, to reflect they were from a CPMG setup.

Regarding bug #21344, (https://gna.org/bugs/index.php?21344) - Handling of in sparse acquired R1rho dataset with missing combinations of time and spin-lock field strengths.

Added system test for bug 21344.

Regarding bug #21344, (https://gna.org/bugs/index.php?21344) - Handling of in sparse acquired R1rho dataset with missing combinations of time and spin-lock field strengths.

This test will fail with:
No intensity data could be found corresponding to the spectrometer frequency of 799.7773991 MHz, dispersion point of 431.0 and relaxation time of 0.14 s.
Data for a dispersion point of 431.0 and time 0.14 does not exist, and so some of the looping in collecting data for calculation must be wrong.
This behaviour and probably its solution is related to bug 21665, "Running a CPMG analysis with two fields at two delay times" (https://gna.org/bugs/index.php?21665).

More incorrect value fixes for the dispersion GUI tutorial in the manual.

The pA and kex values were also somehow incorrect.
