Moved Prediction from Env to Observation. You can now pass your own predictor to the tree observation builder. if no predictor is passed everything stays the same.

added get_many() method to observation builders, base class and derived. Also removed the render() methods in the env base class and railenv

Changed behavior of environment to change action_dict of agents after their input. --> Giacomo please check that this is ok with your implementation

agents keep going forward if motion started, until stopped + RailEnvActions enum + agent.moving flag for the motion status of each agent + penalties for starting/stopping agents, but set to 0

also implies that agents are drawn in their old locations, ie from previous timestep

added a print.out question : why will an agent not move, once he reach it's destination? May he have to move for passing

updated tests after failing
