Importing models from external frameworks

[auduno]

Since training models in javascript/webgl is likely to be slow compared to frameworks utilizing e.g. cuda and cudnn, it would be nice to be able to import trained models from external frameworks such as caffe, theano or tensor flow. I'm assuming only a subset of modules will be supported, but models such as Squeezenet might be possible to port.

Squeezenet looks like a perfect fit! Thanks for the suggestion!
