data consistency between C and Python

[kamikawa]

Hi

My second request.
It took me a while to grasp a differece between "caffe train/test" command and python "classify.py" command.
I think that could cause mistakes of users and common data format should be supported.

1. Input data
   C: database format ( leveldb etc, )
   python : image file
2. mean data
   C: binary proto
   python: numpy format
3. test phase model prototxt (as I mentioned previous topic)

Best regards.

The caffe command and caffe Python module can load exactly the same net to take the same type of inputs -- see #1774. Doing so reproduces the same results with the command line and the caffe.Net interface in Python.

This should be documented better as noted by #1774.
