Anika has done a great job here, and we should merge this into the master once tested by a third party.

I tested

Propose_MALA        = .true.
Delta_t_MALA_sequential = 0.1
Max_Force_MALA_sequential = 5.0

And this works just fine!

For global_tau_MALA with:

Global_tau_MALA_moves   = .true.
N_Global_tau_MALA       = 1
Delta_t_MALA_global_tau =  0.1
Max_Force_MALA_global_tau = 5.0

I get an error, the issue being that Nt_sequential_end=-1

@anika, All seems to be working now. I have also rewritten the documentation for the updating schemes. I have also modified the Hubbard model module such that one can test all the updating schemes (at the exception of the parallel tempering) out of the box, without having to program anything. I did that on the 6 sites lattice with open boundary conditions and consistently obtained the same results with different updating schemes. It would be great if you could go through the documentation. Thanks Fakher.
