…he new fracture aperture is calculated internally, and it is not propagated to the aperture field. For now, the test requires that the pressure difference to be very small.
…. Replacing it by a constitutive relation for permeability. Updated aperture computed internally. Results still validated by analytical solution. Sample file updated.

This PR is the first step for implementing a simplified hydromechanical coupling based on the Barton–Bandis aperture model and a prescribed stress path.
The main change introduced here is the new permeability constitutive law (BartonBandisPermeability) that internally computes fracture aperture, according to the current pressure and normal stress, before updating its permeability.
