iFit/sw_cylinder

 creates the surface of a cylinder in 3D

 [handle] = SW_CYLINDER(r1,r2,R,N, dash) 

 Input:

 r1    Coordinates of the starting point, dimensions are [3 1].
 r2    Coordinates of the end point, dimensions are [3 1].
 R     Radius of the cylinder.
 N     Number of points of the surface mesh.
 dash  If defined either as a single number or a vector [dash N1 N2], a
       dashed cylinder surface will be drawn, with gaps as follows:
           [N1*R(gap)*dash N2*R(dash)*dash].
       Default for dash, N1 and N2 are 0, 4 and 1 respectively.
