CircuitBoard:

--------------------------------------------------------------------------
   Draw a circuit board.
   l is along x, w along y. The board thickness is along z.
   Dimensions are mm. It outputs two vertex and face lists. One has 
   components, the other the circuit board.

   Type CircuitBoard for a demo.
--------------------------------------------------------------------------
   Form:
   [v, f, c] = CircuitBoard( board, component )
--------------------------------------------------------------------------
