I'm working on adding SqueezeNet to PaddlePaddle/models as requested in #532 (closed) .

This initial PR only adds the new model file. You'll note that at lines 75 and 84, I indicate where global pooling layers need to be added. I'm not sure if global pooling is replicable in Paddle 0.11.0 (I see that it's available in Fluid) - any advice would be appreciated.

SqueezeNet, Iandola et al., is described here: https://arxiv.org/abs/1602.07360.
