3605770b68 GCS: Interface to query whether the used diagnose matrix is empty 
=================================================================

Diagnose constraints do not include among others driven constraints. This
function allows to know whether the solver is considering an empty matrix.

dbe917dcc7 GCS: Refactor and additional debug information 
==============================================

In maximum verbose debug mode, information is given about the groups of Sketcher Constraints that the solver is considering for redundancy or conflict.

This is before the popularity contest selects the constraint shown in the solver messages.

The main reason for showing this is to enable to diagnose problems with sketches in which the constraint indicated as the redundant one appears not to
be the right one. Intended for power users with "iteration level" debug mode.

9b11cc086d GCS: Improvement in redundant constraint detection 
==================================================

The solver uses some heuristics to determine the "redundant to remove" and notify it to the user.

Basically it would pick the solver redundant constraint that affects most groups of redundants (popularity contest).

In the simple cases, all the redundants are equally popular and the popularity contest is untied by using the tagid (let say for simplicity it is the number at sketcher level Constraint3, the tagid=3).

This means that in simple cases, the solver systematically decides that the redundant constraint to handle from those showing a linear dependency is the one appearing the last.

This commits changes the way to untie the popularity contest, by giving more priority to those sketcher constraints that need a lower number of solver constraints (in other words,
those constraints that remove a lower amount of DoF). In case of tie, the tagid is then used to break the tie.

At least:

33be143f48 Sketcher: Solver bypass of knotpoints 
Internal geometry knot points, which were added as fixed parameters to the solver according to a previous commit, are tracked in the corresponding bspline as solver level,
without being a parameter to the solver, and upon solving, the position thereof is updated by means of OCC functionality.

This allows to show the knot points and solidarily move them when moving a bspline.
