       addlocap  creates  a  new  capacitor,  and adds it to the list of capacitors pointed to by
       ptfig -> LOCAP. The new capacitor is added in front of the list, and  becomes  itself  the
       list head.
       The type parameter can take two values :

              CAPMIM              for a metal/metal capacitor (the top plate and the bottom plate
                                  layers are different metal layers)

              CAPPNWELL           for a POLY/NWELL capacitor (if available  in  the  technology).
                                  The top plate layer is POLY, bottom plate is NWELL.

       The capa argument is the capacitance value in Farads.
       Two  connectors  are  created each time a capacitor is added, and the tcon and bcon losigs
       are attached to the SIG field of the locon of the appropriate  connector.  The  connectors
       names are tcon  (top plate) and bcon (bottom plate); their direction, DIR, are set to 'P',
       and their TYPE INTERNAL.  For details on the structures, see locon(3) and locap(3).


       addlocap returns a pointer to the newly created capacitor.

              The type is not a legal capacitor type.
