Error when module's qualified name is different from the module file location

[whitews]

Hi Kale,

Thanks for your work on this project, I find it very useful for documenting large classes.

I have a project where, via __init__ files, the qualified names differ from the file path for files containing some class definitions. When I try to add .. autoclasstoc:: to an existing RST doc (that successfully builds prior to adding), I get a ModuleNotFound error. For example, I have a RectangleGate class that has the qualified path flowkit.gates.RectangleGate and would be imported like:

from flowkit.gates import RectangleGate

but the actual file path to the module where the class is defined is:

flowkit/_models/gates/_gates.py

This was a working docs build prior to adding the autoclasstoc line for this class. The RST file that triggers the error:

RectangleGate Class
===================

.. currentmodule:: flowkit.gates

.. autoclass:: RectangleGate
    :members:

    .. autoclasstoc::

Full stack trace:
