Optimized generic computation of scaled Jacobian range in MElement. Adapted AnalyseCurvedMesh plugin as well as generic distoShapeMeasure to use it. 

Modification of NearToFarField of Mohamed to print the far field vector instead of modulus in matlab file.
To test!

Better handling of (co)homology computation in selected dimensions only. Various cleanups and documentation of (co)homology stuff.

Added possibility in homology solver parser interface to select (co)homology space base dimensions to save; Added option to select (co)homology basis physical groups numbers and debug options to HomologyComputation plugin.
