**Bugfixes**
- Fix ``__update()`` method in ``EClass`` when many elements are added at once.
This case occurs when ``append()`` is used on an ``EClass`` in order to add
many ``EStructuralFeature``.
- Fix shared content for mutable ``EDataType``. When mutable EDatataypes are
defined (e.g: ``EStringToStringMapEntry``), each default value was pointing to
the same shared value (exactly the same thing that when ``def x(self, n={})``).
The default_value is now computed, if a special attribute is set, the default
value is always created as a new empty value.
- Fix default value for property instances accessed after the instance creation.
**Miscellaneous**
- Add missing ``EFeatureMapEntry``.
- Add missing LICENCE file in dist package.
- Add default value managmeent for 'instanceClass' derived datatypes.
