 * 
 * The core of state machine behaviours are 5 functions that are automatically called whilst in an animator state and 2 functions that are automatically called whilst in a sub-state machine. 
 * Commented out versions of some of these functions are added to new state machine behaviours when they are created. These functions are OnStateEnter, OnStateUpdate, OnStateExit, OnStateMove and OnStateIK. 
 * The additional functions for sub-state machine transitions are OnStateMachineEnter and OnStateMachineExit.
 * All of these functions have 3 parameters passed to them: an Animator, an AnimatorStateInfo and the layer index
 * 
 * The Animator parameter is a reference to the specific animator that this state machine behaviour is on. 
 * For example, this could be used to set the values of animator parameters that were only necessary in this state, such as those for a blend tree.
 * The AnimatorStateInfo is the current info for the state that the state machine behaviour is on. It is the equivalent of writing animator.GetCurrentStateInfo(layerIndex); 
 * This can be useful in operations that involve the normalised time of the clip.
 * The layerIndex is the layer the state machine behaviour’s state is on. For example, zero for the base layer, one for the first, and so on.
 * 
 * As with MonoBehaviours, the functions of a StateMachineBehaviour are called under specific circumstances.
