+#Should call method if a key was pressed
+#Variales: isPressed, actionPerformed
+#To make sure that the key only get's pressed once when holding a button down, Two variables are needed.
+#isPressed: If not pressed, call method on next keypress
+#actionPerformed: If method was called and key is still down, do not call method no more
+#Input instances will be allocated before gameplay, therefore: isPressed and actionPerformed will be initialized false.
+
+#methods: init, update
+#update: Will be called when there is a change in this actual keys state. With respect to the input class behaviour, 
+#update will evaluate if it's corresponding method should be called or not
+#param: state tells if the key is down or up.
+
+
+#Four possible preconditions: is not pressed and key is up.   ->  Set isPressed to false.
+#                             is not pressed and key is down. ->  
+#			      is pressed and key is up.
+#			      is pressed and key is down.
