	Compares the player's attempt with the randomly generated sequence
	and return the results in a list.
	
	If a given coulour appears more than once in either sequence, we'll
	have a problem so we use a counter on each colour so that if a colour
	appears twice in one sequence and just once in the other, it will be
	counted as one in the results, for example, if the goal is :
	
	[1, 2, 3, 4, 5, 6] and the player's guess is [2, 1, 1, 1, 1, 1]
	
	the results will be [0, 2]
