Since the Deck* family of classes have changed their interfaces to no
longer use shared_ptr, a lot of code broke. This patch fixes all
problems in tests, other signatures and accesses to now use the new Deck
interfaces.
- Create a new shared library libcopmparser with small files cxxxx
which wrap general Cxx classes with C linkage.
- Added Python packages & modules, based on Python ctypes and the
ert.cwrap package.
