Specified inputs are not in an expected order #111

I think this TODO may relate: https://github.com/csu-hmc/opty/blob/master/opty/tests/test_direct_collocation.py#L180

Both Timo and I saw this when we started solving the bicycle problem with multiple inputs.

See: brocksam/muscle-driven-bicycle-paper#12 (comment)

was not due to the Problem.plot_trajectories() method being incorrect but due to not using the internal order of the inputs that opty creates. I fixed that in the bicycle muscle paper.

I had a problem with plot_trajectories, see discussion #186. I had 3 specified symbols (a torque acting on a ball) and one known trajectory (the time appearing explicitly in the EOMs). What do I need to do? Thanks!
