Spiro simulates a spirograph. There is a still ellipse and a
moving circle with a virtual pen at some position on (or beyond)
its radius. The moving circle can be inside or outside of the
still circle.

Since no physical rings are involved it is OK to move a bigger
circle inside a smaller one!

Controls:

Use arrow keys to move from one command to another

Go		 Draw pattern using current settings
Exit	 Leave spiro
Cls 	 Clear Screen
XC		 Set x coordinate of still ellipse
YC		 Set y coordinate of still ellipse
