changes to append_factor which give more than 2x speedup on my data. Matrices in As are no longer copied/edited/replaced each time they need to be changed, but created once and then updated in place.

Cleanup with NonlinearConstraints to make the active() function do thresholding for inequality constraints, rather than constraint function itself.
testSQP now has all tests active and passing.
Added greaterThanOrEqual() for vector comparison.

Added a function for the SQPOptimizer that will iterate until convergence. At the moment, the convergence conditions are quite simple (error below threshold or too many iterations). The system does, however, strictly limit the number of iterations.

Added basic inequality constraint handling to NonlinearConstraint. Demo still in progress, but now constraints are explicitly handled as either equality or inequality constraints, with an active() function to determine if it is necessary to use the constraint.
Created testOrdering for new subtract() function to remove parts of an ordering.
