Duplicate object descriptions

[CasperWA]

Follow-up task from #415.

There are duplications in some methods or similar that are defined both in the C code and included Python files.
The resulting Sphinx warnings may also be due to overloaded functions, something that Sphinx and AutoAPI cannot handle.

What methods are you referring to?

In general I think we want to use the same name in C and in the Python bindings for the same function (except that we in C prefix functions with dlite_).

From building the Sphinx documentation:

.../dlite/pydoc/autoapi/dlite/dlite/index.rst:1444: WARNING: duplicate object description of dlite.dlite.Instance.save, other instance in autoapi/dlite/dlite/index, use :noindex: for one of them
.../dlite/pydoc/autoapi/dlite/dlite/index.rst:1700: WARNING: duplicate object description of dlite.dlite.get_instance, other instance in autoapi/dlite/dlite/index, use :noindex: for one of them
.../dlite/pydoc/autoapi/dlite/index.rst:1490: WARNING: duplicate object description of dlite.Instance.save, other instance in autoapi/dlite/index, use :noindex: for one of them

And I indeed found the get_instance() function defined in both a C file as well as an included Python file, which extends a C file, supposedly?
As I don't fully understand these relationships concerning building the package, I am unsure exactly how to be more specific.
