[179]1%'sub_field': combines two input fields
2%
3% the two fields are subtstracted when of the same nature (scalar or
4% vector), if the coordinates do not coincide, the second field is
5% interpolated on the cooridintes of the first one
6%
7% when scalar and vectors are combined, the fields are just merged in a single matlab structure for common visualisation
