Can give the running demo

how to run decoder_A.h5 or encoder.h5

[Clorr]

To run the demo, you have to setup your environment (If you check my pull request, you will find a Dockerfile with the tools needed).

Once this is done, you will have to run python ./script.py from the code folder. This script will take all pics in data/trump and apply a new face on it. The resulting images will be in a folder named output

Note that my Dockerfile still has issues, and you will have to modify scandir and the mkdir parameters
