Bug corrections: i) boundless variables wasn't detected properly,
ii) the sigma_i + mu_i wasn't done correctly, mu_i was added at
each lambda_j variable instead of only once at the end, iii) the
initialization of parameter df in lmm_variable_new was 1 and it must
be 0.0, iv) the function for Reno has some workrounds that doesn't
seem to work correctly (this last one to be continued...).
Thanks to Arnaud Legrand.
