Mapping Between mox.file and Local APIs and Switchover

Python: local file operation APIs of Python. The APIs can be shifted to the corresponding MoXing file operation APIs (mox.file) by one click.
mox.file: file operation APIs of MoXing Framework. The APIs correspond to the Python APIs.
tf.gfile: TensorFlow APIs with the same functions as MoXing file operation APIs. In MoXing, file operation APIs cannot be automatically switched to TensorFlow APIs. The following table lists only the APIs with similar functions.
