Started to implement the relaxation dispersion analysis specific calculate() method.

This will be used to calculate the R2eff/R1rho values for the fixed relaxation time period data types
and is equivalent to Sebastien Morin's relax_disp.calc_r2eff user function deleted at r19580
(see http://thread.gmane.org/gmane.science.nmr.relax.scm/17336).

The 2D Grace plots of the exponential curves are now skipped for the fixed relaxation period data types.

This is in the relaxation dispersion auto-analysis.

Fix for the calculation part of the relaxation dispersion auto-analysis.

This is for the fixed relaxation period data types.

The relaxation dispersion class variables for the experiment types are now used for all comparisons.

This should avoid random bugs.

Fix for some RelaxError printouts in the relaxation dispersion specific code.

The Relax_disp.test_hansen_cpmg_data_fast_2site system test now uses the R2eff model.

The equivalent slow exchange system test also uses the model. This model will be used to find the
R2eff values from the fixed relaxation time period data.

The relaxation dispersion scaling matrix assembly now uses lib.mathematics.round_to_next_order().

This allows the printed out I0 values for the optimisation of the exponential curves to be easier
to scale back to the real value.

The relax_fit analysis now uses lib.mathematics.round_to_next_order() for the scaling matrix.

This allows the optimised I0 value to be better understandable in the printouts.

Created the lib.mathematics relax library module.

This currently contains two functions, order_of_magnitude() and round_to_next_order().
