TensorFlow feature extractor using tf.slim and models/slim.
Core functionalities are loading network architecture, pretrained weights,
setting up an image pre-processing function, queues for fast input reading.
The main workflow after initialization is first loading a list of image

through the network with `feed_forward_batch`.
