Big bug in HyperNet_ComponentOccurrences::Locator::progress().

* Bug: In HyperNet_ComponentOccurrences::Locator::progress(), (Collection
    locator), the _netOccurrenceLocator (which progess along the various
    Net occurrences of the HyperNet) was not in synch with the
    _componentOccurrence locator of the current net. It was pointing
    to the *next* net occurrence.
      The result was the generation of a path for the net commponents
    that was incorrect (it was the path of the *next* net occurrence),
    and making Occurrence constructor throw an exception.
* Change: In Cell::flattenNets(), DeepNet::_createRoutingPads(),
    Occurrence::Occurrence() and UpdateSession, added even more trace
    informations.
