pretrained networks for deep learning applications

Pretrained networks for a variety of problems.
WBIR networks are named wbir*
put them all in a folder called "models" then see create_wbir_models.R for how to load them
wbir_random_vgg_3d --- 3dvgg initialized with random weights
wbir_resnet_vgg_weights --- resnet trained to mimic 2d pseudo vgg activations
wbir_vggtrue3d -- 3d egg trained to mimic 2d pseudo vgg activations
wbir_brain_age_weights -- weights for brain age
wbir_pseudo_vgg_ -- 2d vgg transferred to 3d
qc networks
