Help with Reviewing my GSoC project

[TARUN GABA]

Hi all

I have been working on a GUI for PyDy VIsualizer, 

which can be embedded inside the IPython notebooks.

The new GUI has many new features over the earlier one,

and support features like rerunning PyDy simulations,

from within the GUI itself(and many more!).

I need help with reviewing the code,as well as the GUI.

Please have a look at this PR:

https://github.com/pydy/pydy/pull/82

The new implementations require installing the IPython master,

I have added the build instructions in the PR description.

Please have a look at the the GUI. Feel free to contact me If you have difficulties

building the requirements. and most importantly, Please help me with

the reviewing and suggestions for improvements! 

Here is a snapshot of the GUI inside IPython notebook:

(an eye candy for IPython enthusiasts :-D )
