Correct exception catching when creating invalid occurrence in Isobar.

* New: In CRL Core, in PyCellGauge, add the missing methods.
* Bug: In Isobar, PyOccurrence_create(), the HTRY/HCATCH block was not
    enclosing the constructor of Occurrence, which can throw exceptions.
    When an exception was thown the Python interpreter just terminate
    with the cryptic message:
      "Fatal Python error: Py_EndInterpreter: thread still has a frame"
    Reminder to myself: when such a message occurs, it means that the
    interpreter did encounter a problem, but it's related to the isobar
    interface.
