Playground code to start with.
Committing stylistic fixes.
Addressed most comments on my previous Git push

I addressed all (except one) of mtomwing's comments. As to the question
"Why are you only looking at the first attribute ...?", at the moment, I
do not know too much about the structure of the Plugin Modules yet. As
far as I am aware, there is going to be one class that contains
information about the plugin. From observation thus far, that class is
the first attribute of the Module. If it is known that there are other
cases (one Module contains multiple plugin classes, global attributes
will be defined in the Module before the class definition, etc), I will
make an effort to modify the algorithm.

For dideler, I removed the comments I deemed "obvious" but I'm not sure
if our definitions of "obvious" agree. The example you gave was
amazingly obvious (my vocabulary fails me). I usually put comments up
when I feel something must be explicitly stated. I'm not entirely sure
where this feeling comes from though.

Also, noted. In later stages, I'll move unnecessary things to
appropriate locations. Though if __init__ only does "trivial"
initialization, how does the "rest" of the initialization happen? I'm a
tad confused.

For zxiiro, I hope my variable names are rather self explanatory. Please
just say if any aren't, and I'll try to think of a better name.

I think I added the license properly?
Renamed 'nodes' to 'plugins'.
Removing redundant tox.ini
Removing the playground and adding manage.py as suggested.
Added a module generator to manage.py.
Temporarily commenting out unfinished code to allow Travis to succeed.
Is now able to handle __init__.py files properly. (As far as I am aware)
removed a useless line.
Moving manage.py to framework/plugins/
