    cuDNN R4
*   Added a `contrib/` directory for unsupported or experimental features,
    including higher level `layers` module
*   Added an easy way to add and dynamically load user-defined ops
*   Built out a good suite of tests, things should break less!
*   Added `MetaGraphDef` which makes it easier to save graphs with metadata
*   Added assignments for "Deep Learning with TensorFlow" udacity course
