*   Added an op for QR factorizations.
*   Divides and mods in Python API now use flooring (Python) semantics.
*   Android: pre-built libs are now built nightly.
*   Android: cmake/gradle build for TensorFlow Inference library under
    `contrib/android/cmake`
*   Android: Much more robust Session initialization code.
