Analyzing an __init__.py in cwd crashes Pyan

[Technologicat]

The scope naming internals of objects at the top level of a module seem to have changed somewhere between Python 3.4 and 3.6.

This code used to work in Python 3.4 (pyan/analyzer.py, method analyze_scopes):

ns = "%s.%s" % (parent_ns, sc.name) if len(sc.name) else parent_ns

but in Python 3.6.8, I'm now getting names like ".some_top_level_object" (note silly leading dot).

Now parent_ns is empty, and the object name is returned in sc.name. It used to be the other way around.

Seems this needs code to handle both cases...

...or maybe it's the fact I'm now trying to analyze a nontrivial __init__.py? Debugging...

[Technologicat]

...which is in the cwd (see anutils.py, function get_module_name).

Yep, analyzing an __init__.py in cwd was the actual culprit.

Let's document also the fact that nontrivial here means that the __init__.py defines functions and/or classes, so something for Pyan to pick up.
