__init__.py imports makes things confusing

[jbfaden]

Right now there's an init.py which imports five names from autoplot.autoplot, which makes it confusing because you can say both:

from autoplot import javaaddpath  # and
from autoplot.autoplot import javaaddpath

I'm not sure what the motivation was*, but it seems misguided and confusing now. * "Allow 'from autoplot import javaaddpath'" says the documentation.

Be careful with changing this b/c a change may break existing code.
