Python object construction not straightforward

[ma-laforge]

After running a few tests, it appears there are 2 ways to construct an object.
Let us assume a python module was imported in Julia:

@pyimport MyModule as mm

1. If your Python object is derived from "object", you get the nice call syntax:

Python:

class MyObj1(object): ...

Julia:

mm.MyObj1([constructor args...])

2. If your Python object is not derived from "object", the syntax is not as nice:

Python:

class MyObj2(): ...

Julia:

pycall(mm.MyObj2, PyObject, [constructor args...])

My experiments show the two constructor syntaxes cannot be interchanged.

Though a little confusing, this is not so bad. It might be nice to have it mentioned in README.md.

Great module!

This difference will go away in Julia 0.4 once I can make all PyObjects callable, I think (see #101).

Sounds good to me. I guess I will close the issue. Thanks.
