Fix some bugs and add .gitignore.
(1) Fixed a bug that num_depots was not passed as an argument to the forward method of actor when executing MDCVRP\VRP_Rollout_train.py.
(2) Fixed a bug casting a torch.sensor(not numpy.ndarray) to a torch.sensor with torch.from_numpy function.
(3) Add .gitignore for future git capacity limit.
