* New: In bootstrap/coriolisEnv.py, add the "etc" directory to the
    PYTHONPATH as initialization are now Python modules.
* New: In Hurricane/analogic, first groundwork for the integration of
    PIP/MIM/MOM multi-capacitors. Add C++ and Python interface for the
    allocation matrix and the list of capacities values.
* Change: In Hurricane::RegularLayer, add a layer parameter to the
    constructor so the association between the RegularLayer and it's
    BasicLayer can readily be done.
* Change: In Hurricane::Layer, add a new getCut() accessor to get the
    cut layer in ViaLayer.
* Change: In Hurricane::DataBase::get(), the Python wrapper should no
    longer consider an error if the data-base has not been created yet.
    Just return None.
* Bug: In Isobar::PyLayer::getEnclosure() wrapper, if the overall
    enclosure is requested, pass the right parameter to the C++ function.
* Change: In AllianceFramework, make public _bindLibraries() and export
    it to the Python interface.
* Change: In AllianceFramework::create(), do not longer call bindLibraries().
    This now must be done explicitely and afterwards.
* Change: In AllianceFramework::createLibrary() and
    Environement::addSYSTEM_LIBRARY(), minor bug corrections that I don't
    recall.
* Change: In SearchPath::prepend(), set the selected index to zero and
    return it.
* Change: In CRL::System CTOR, add "etc" to the PYTHONPATH as the
    configuration files are now organized as Python modules.
* New: In PyCRL, export the CRL::System singleton, it's creation is no
    longer triggered by the one of AllianceFramework.
* New: In CRL/etc/, convert most of the configuration files into the
    Python module format. For now, keep the old ".conf", but that are no
    longer used.
      For the real technologies, we cannot keep the directory name as
    "180" or "45" as it not allowed by Python syntax, so we create "node180"
    or "node45" instead.
      Most of the helpers and coriolisInit.py are no longer used now.
    To be removed in future commits after being sure that everything
    works...
* Bug: In AutoSegment::makeDogleg(AutoContact*), the layer of the contacts
    where badly computed when one end of the original segment was attached
    to a non-preferred direction segment (mostly on terminal contacts).
      Now use the new AutoContact::updateLayer() method.
* Bug: In Dijkstra::load(), limit symetric search area only if the net
    is a symmetric one !
* Change: In Katana/python/katanaInit.py, comply with the new initialisation
    scheme.
* Change: In Unicorn/cgt.py, comply to the new inititalization scheme.
* Change: In cumulus various Python scripts remove the call to
    helpers.staticInitialization() as they are not needed now (we run in
    only *one* interpreter, so we correctly share all init).
      In plugins/__init__.py, read the new NDA directory variable.
* Bug: In cumulus/plugins/Chip.doCoronafloorplan(), self.railsNb was not
    correctly managed when there was no clock.
* Change: In cumulus/plugins/Configuration.coronaContactArray(), compute
    the viaPitch from the technology instead of the hard-coded 4.0 lambdas.
      In Configuration.loadConfiguration(), read the "ioring.py" from
    the new user's settings module.
* Bug: In stratus.dpgen_ADSB2F, gives coordinates translated into DbU to
    the XY functions.
      In st_model.Save(), use the VstUseConcat flag to get correct VST files.
      In st_net.hur_net(), when a net is POWER/GROUND or CLOCK also make it
    global.
* Change: In Oroshi/python/WIP_Transistor.py, encapsulate the generator
    inside a try/except block to get prettier error (and stop at the first).
