add mobilenet

[qingzhouzhen]

This mobilenet implements article MobileNets: Efficient Convolutional Neural Networks for Mobile Vision Applications
It speeds up training and scoring in ImageNet 2012 with CPU version but not GPU
I will try to implemented depth-wise conv using cuda kernel

How about the final acc compared with the original network?

[qingzhouzhen]

I am training on my machines, I did not get the final accuacy file, but currently it is low than normal convulution.

I get current result as below @feiyulv :
