get_score()

def rosbag_tools.helpers.get_score	(		evaluated_variable,
			max_variable,
			scores
	)

Calculate the score from the evaluated_variable.

Args:
    evaluated_variable: Float of the variable to be scored.
    max_varibale: Float of the maximum value that needs to be undershoot to
                  score.
    scores: List of Floats of the returned scores (length should be 4).
Returns:
    The score, that one gets for the evaluated_variable.
