Cannot use .. autovariant_(function|method)

[pganssle]

I believe this is a problem with the import_object mechanism, for some function in example_variants.py, if you have:

from variants import primary

@primary
def func(a, b):
    """The primary function"""

@func.variant('onearg')
def func(a):
    """A variant with only one argument"""

And you create a document like so:

=======
Example
=======

.. autovariant_function:: example_variants.func.onearg

You'll get an error failing to import example_variants.func.onearg.
