batch evaluation

[dmenig]

Hi. I spent two days working on this repo in order to render batch evaluation possible. I've created a set of parallel functions (test_images next to test_image, proposal_layer_batch next to proposal_layer etc...).

It isn't made for training, but it can make the utilization of this repo much easier in deployment.

I spent so much time on it I thought I'd suggest the pull to you.

Thanks for your work anyway.

Sounds useful. I will take a look. Thank you

Thanks. i'd be happy to discuss my choices if you have thoughts. For example I had to keep some layers (fc7 for instance) on a sequential evaluation fashion since its inputs can theoretically be of different sizes throughout a single batch.

Would you like to extend the training code to support batch too so that we don't need extra *_batch?
