Adding a Python 3 Kernel to Datalab. (#1344)

chmeyers · web-flow · commit f1160b081da4 · 2017-05-01T11:00:38.000-07:00
* Adding a Python 3 Kernel to Datalab. Installs Python 3 and py3 versions of our supported packages, including the python3 jupyter kernel, and adds a dropdown to the notebook page to allow users to switch kernels. Fixes #902 * Fix merge error. * Changes based on review comments. * Fixing minimum toolbar width. * Fixing build error.
