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.

Modified systemtest test_bug_9999_slow_r1rho_r2eff_error_with_mc to save data arrays.

This is to prepare a profiling script.
