Calculates mean and time dependence of n-fold order parameter and writes maps to files.

<sigma matrix file> refers to a file that describes the cross interaction $\sigma$ values. It is formatted as described below:
<arbitraty name for species 1> <sigma_11> <sigma_12> <sigma_13> … <sigma_1n>
<arbitraty name for species 2> <sigma_21> <sigma_22> <sigma_23> … <sigma_2n>
...
<arbitrary name for species n> <sigma_n1> <sigma_n2> <sigma_n3> … <sigma_nn>
