* nero/src/ : 

- New Feature : to allow routing reuse, NeRo is now able to build the
       abstract of a mega-cell. That is, adds the relevant CALUx and TALUx
       describing the interface at top-level.
   - Bug : in the abstract generation, the intermediates TALUx metals of
       a stacked VIA where forgotten. For example, when there is a VIA34
       on top of a VIA23 you must have obstacles in TALU4 and TALU2 but
       also a "dot" obstacle in TALU3. "Dot" obstacle are added only when
       we process a layer in the preferred routing direction, otherwise
       we would create a dot at each routing grid point...
