Tutorial for Relaxation dispersion analysis r1rho fixed time recorded on varian as sequential spectra

Intro

This tutorial presently cover the relax_disp branch.
This branch is under development, for testing it out, you need to use the source code. See Installation_linux#Checking_out_a_relax_branch.

This tutorial is based on the analysis of R1rho data, analysed in a master thesis.

The spectra is not recorded interleaved, but as a series of spectra with experimental changes.
