Change invocation order in Tower of Hanoi to match with animation

[bharatagarwal]

Currently, the animated solution of Tower of Hanoi moves the tower from the first pole to the last pole.

The invocation of move_tower with from_pole = A, to_pole = B, with pole = C moves the tower to the second pole instead. This difference in to_pole makes it confusing to reconcile the animation with the code.

I agree that from_pole = A, to_pole = C is needed to agree with the animation. However the animation has a height of 4 (rather than 3). We can make this change too but do you think it's worth significantly increasing the length of the output to match the animation?
