Changes Between v4 and v5:

Make model

Instead of programmatically generating the common model each time we run the script, we have now generated the model once, saved it as a csv file, and now simply load it.

v4:

% Make model
nElec = 20;
imdl = mk_common_model('d2d1c', nElec); % of inv_model 2D data structure
%imdl = mk_common_model('b3cr', nElec) % of inv_model 3D data structure

v5:

To be determined.
