Further information
This function tests the current status of a constraint. At its creation a constraint is added to the current problem, but using the function sethidden it may be hidden. This means, the constraint will not be contained in the problem that is solved by the nonlinear solver but it is not deleted from the definition of the problem in Mosel.
