This patch includes change in func_mf, func_local_tm, func_diff, func_all, dfunc_mf, dfunc_local_tm,
dfunc_diff, dfunc_all, d2func_mf, d2func_local_tm, d2func_diff, d2func_all functions of class Mf in
a file maths_fns/mf.py. The functions were modified in order to handle data for more interactions.
Due to the equality of (d,d2)ri and (d,d2)ri_prime variables, the (d,d2)ri_prime were replaced by
(d,d2)ri and the equality was removed. Moreover, (d,d2)ri was redefined as a cumulative sum of
individual interaction contributions to the total relaxation rate or corresponding derivatives.
