Regarding Implementation of F2DC

[ASZAN-Aryan]

I'm just a novice but I tried Implementing the code and I found some issues:
(I only tried using the Office_Caltech_10 dataset first)

1. Missing:
   a) VGGNet_DC.py
   b) gumbel_sigmoid.py
   c) WRN.py

2)ResNet_DC.py returns 5 values but f2dc.py expects 7
either the code is not up to date or there is issue with ResNet version

Thank you for the help!
