Test 2: ProGAN training

ProGAN is a technique developed by NVIDIA Labs in 2017 to improve both the speed and stability of GAN training. Describe the process of training ProGan: 

1. basic overall idea
2. generator architectures for the first stage of the ProGAN training process
3. discriminator architectures for the first stage of the ProGAN training process
4. overall structure of the generator and discriminator after the full progressive training process is complete
