update models

[bodokaiser]

We want to implement following models (ordered after priority):

1. FCN
2. SqueezeNet
3. SegNet
4. PSPNet
5. RefineNet

Removed models (because too big, too complicated or not much information):

• DeepLab

FCN

We use the this VGG-8 implementation which can be viewed as graph.
