Running MPS algorithms

The MPS algorithms are run from the commandline using a parameter filename as an argument.
If no argument is given, the default parameter file is assumed to the be name of the simulation
algorithm appended with ‘.txt’.

Therefore

mps_genesim
mps_snesim_tree
mps_snesim_list

will be equivalent to

mps_genesim mps_genesim.txt
mps_snesim_tree mps_snesim_tree.txt
mps_snesim_list mps_snesim_list.txt
