CYLINDERSURFACEAREA  Surface area of a cylinder.

   S = cylinderSurfaceArea(CYL)
   Computes the surface area of the cylinder defined by:
   CYL = [X1 Y1 Z1  X2 Y2 Z2  R], 
   where [X1 Y1 Z1] and [X2 Y2 Z2] are the coordinates of the cylinder
   extremities, and R is the cylinder radius.
   The surface area of the cylinder comprises the surface area of the two
   disk-shape end caps.

   Example
     cyl = [0 0 0  1 0 0  1];
     cylinderSurfaceArea(cyl)
     ans =
        12.5664
     % equals to 4*pi
