spanarc


             spanarc(a, b, c, n)  
 
    return N points equally spaced along circular arc ABC.  Each of A,  
    B, and C is a point in M>=2 dimensional space.  That is, A = [x,y]  
    or [x,y,z], etc.  A, B, and C may also have trailing dimensions in  
    order to generate points along several arcs simultaneously.  The  
    result has dimensions dimsof(A,B,C)-by-N.  
    With non-nil, non-zero cont= keyword, the points will fall along the  
    circle from C to A continuing the arc ABC and completing the circle.
