* New: Isobar::PyAttributesHolder, a PyObject with only a dictionary
to hold the attributes associated to a DBo.
* New: Isobar::PyHolderProperty, the Property that encapsulate
PyAttributesholder.
* New: Isobar::PythonAttributes, the extension to simplify the
management of the PyAttributesholder.
* Change: In PyEntity, now use a dedicated tp_getattro and tp_setattro
to delegate the Python attribute access towars the PyAttributesholder.
* New: In hurricane/doc & documentation, update docs regarding Python
attributes managment.
Main list of ports:
* Replace deprecated operator '<>' by '!='.
* To check if a list is empty, do not compare to [], but check it's
length instead.
* Do not make a class inherit indirectly twice from the same base class.
* Hurricane physical object constructors uses DbU::Unit as arguments,
seen as int in Python, so they will not match float. Unfortunately
the calculation often gives float. So explicitely cast them into
int. This is due to a change of behavior in Python. Now, 3/2
gives 1.5 (float). To get the previous one use: 3/2 -> 1 (int).
* dict.keys()[0] no longer work, instead use list(dict.keys())[0].
In SelectorCriterion & SelectorCriterions, when selecting a Net occurrence,
we where storing the Net only. This was fine if the Net was belonging to
the Cell's top level. But when it was an occurrence of a non-top level
net, this was creating the elusive incoherent Occurrence problem.
Now we truly store the occurrence of the Net, to be accurate, the root
of the HyperNet.
* Change: In SelectorCriterions::add(), the Net* argument is replaced
by a Occurrence of Net. Must be an HyperNet root occurrence.
Same goes for SelectorCriterions::remove().
* Change: In CellWidget::select(), when called with a Net occurrence,
select the whole HyperNet components.
* Change: In NetSelectorCriterion, now use a Net occurrence instead
of directly a Net. Must be an HyperNet root net occurrence.
* Change: In EtesianEngine::toColoquinte(), not only compute the ratio
of DFF versus the total number of gates, but also the ratio in
term of area. As the DFF are usually very big cells compare to
combinatorial one, the direct gate ratio could be misleading as
to the "weight" of those cell in the design.
