00027 // Description : A point on line joint constrains a point on one
00028 //               body to only move along a line attached to another
00029 //               body. 
00030 //               The starting point of the joint is defined as the
00031 //               anchor point. The line through this point is
00032 //               specified by its direction (axis) vector.
