Hello All

In math and physics we typically use terms clockwise and
anti-clockwise and not right and left for rotation. This change will
make it easy for kids to learn the terms that they will eventually use
in math and physics anyway.

The change I am proposing is to alias right rotation with two more
names: clockwise or cw and left rotation with two more names:
anticlockwise or acw.  Programmers who are currently using left or
right can continue to do so.

Based on the documentation supplied by Steven, I agree that everyone
programming is using right and left but it might be in the right
direction to program using clockwise and anticlockwise.

Thanks,
Ravi
