Create Binder-compatible dependency files

[poldap]

Create dependency files so that we can link to https://mybinder.org/ and it prepares an environment where we can run the example Jupyter Notebook.

For now it seems the simplest is to have the basic Jupyter installation on a requirements.txt file and the installation of the IJavaScript kernel and its registration to Jupyter on a postBuild file (a simple BASH script).
