/**
 * Extension of a {@link ActiveSetQPSolver} allowing to explicitly disable or enable components of
 * {@code x} when solving the problem.
 * 

 * Instead of resizing the problem's matrices, the user can simply indicate which component is to be
 * ignore during the next {@link #solve(DMatrixRMaj)}, cutting computation time to a similar
 * magnitude compared to the problem being resized in a compact form. This has the advantage from
 * the user's perspective to preserve a fixed indexing for each variable component without
 * increasing computation time.
