Value of ConstraintFcn cost print incorrect when the constraint is time based

[Kev1CO]

The output of sol.print_cost() returns an incorrect value of ConstraintFcn.STATE_CONTINUITY or ConstraintFcn.CUSTOM when time is involved. This error comes from the solution.py file.

`class Solution:

 def _get_penalty_cost():
        for idx in range(le(penalty.node_idx)):
                t0 = PenaltyHelphers.t0(penalty, idx, lambda p, n: self._stepwise_time[p][n][0]`

self._stepwise_time[p][n][0] the [0] is where it creates a mistake
