Abstract interface for the constraint portion of a constrained nonlinear system for constraints that support computing a solution component derivative as a multi-vector.
This class extends the LOCA::MultiContinuation::ConstraintInterface to support constraints that support computing the entire derivative with respect to the solution components (x) and storing the resulting derivative as a multivector. This interface adds one additional method, getConstraintDerivativesX(), that returns this derivative. Additionally, it implements the applyConstraintDerivativesX() methods using standard multi-vector operations.
