CenterStage Object Class:  Vectors
Subclass of:  Arrows

The Vectors class allows you to specify arrows by giving a basepoint and an 
offset vector from that basepoint.  You can specify colors and other 
characteristics on a vector-by-vector basis, or for groups of vectors.

The Vectors class supports the the standard directives, plus the following:

    Vectors {vector list}

        The vector list should be formed by pairs of points.  The first of 
        each pair represents the basepoint of the vector, and the second 
        gives the vectors direction and length.  (The vector's tail will 
        be at the basepoint and its head at the sum of the two points).

	The vector list can specify vector attributes using the "<-" 
	symbol, just as in the Arrows directive for the Arrows class.  
	Vectors support the same attributes as the Arrows class.
	
The Vectors class also supports the ArrowHead, ArrowScale and ArrowMaxLen 
directives of the Arrows class.
