/* Further Adventures

 *

 * 1) Change the amount by which the point is moved

 *    by altering the x and y properties of

 *    the object literal passed to the move function.

 *

 * 2) Write a reflectX function that reflects

 *    a point in the x-axis, returning the new point.

 *

 * 3) How about a rotate90 function that rotates

 *    the point by 90 degrees anticlockwise

 *    around ( 0 , 0 )?
