fix findFixedPoint gradient
just decided to unvectorize.  saving now so I don't lose anything clever
pendulum example runs nicely enough, but have to check for correctness
add a 'deleteNonlinearConstraint' function to NonlinearProgram
add the first test case for deleteNonlinearConstraint
fixed discretization bug.  optimized a few simple things using the profiler
brought pendulum value iteration parameters over from old example.  (and added wrapping)
add more test cases to deleteNonlinearConstraint. add 'updateNonlinearConstraint'
add 'deleteLinearConstraint' to NonlinearProgram
added function handle visualizer and cleaned up xcubed example (to live in one file)
added grid world example
adding double integrator example
