connect:

---------------------------------------------------------------------------
   Connection of two state space systems. The connection is

   e -> f

   The connection matrix is lists the indices of the matching outputs
   of e and inputs of f. For example

   u       (4,1)           y (3,1)
    f                       e

   c might be [1 1;1 3] which means that output 1 of y goes into input 1
   of u. Output 3 of y also goes into 1 of u.

   c is [uF;yE]

   Empty c implies parallel connection with separate inputs and outputs:

      -------
   -  |  f  | --
      -------

      -------
   -  |  e  | --
      -------
   
---------------------------------------------------------------------------
   Form:
   g = connect( e, f, c )
