For the upcoming Stepanov-Sinha addition, we need to link in the option of including the second order magnetic form factor term

Hi Sam,

Thats right, first idea would be to simply add a new columns to the .mf files which could then be read at second order terms.
However, in any case one needs to add these additional functionalities.
For the beginning, you could simply add new attributes to the existing objects.
