`x0`	Initial iterate
`v`	weights for first set of constraints
`w`	weights for second set of constraints
`plist1`	list of projection functions for first set of constraints; each takes a single point and returns its projection
`plist2`	list of projection functions for second set of constraints; each takes a single point and returns its projection
`f`	objective function
`df`	gradient of objective function
`h`	Function handle for output mapping
`hgrad`	Handle for output mapping Jacobian
`qn`	number of secants
`tol`	convergence tolerance
`max_iter`	maximum number of iterations
