Mapping network #2

Hi, I was looking at your code (I'm also thinking of implementing pi-gan) and had questions about the mapping network.

What is the idea behind the EqualLinear module?
Why are you normalizing the latent vector before passing it through the network?

As far as I can tell neither of these steps is mentioned in the paper so if you have another source for those steps that would be really helpful. Thanks!

@sidmani Hey Sid! Glad to meet someone else fascinated with the intersection of Nerf and GANs! I actually copied the mapping network code from my stylegan2 implementation. I'll correct it to match the paper's this week, after I code up the progressive growing part of the discriminator

Great, I haven't read stylegan2 yet so I'll take a look.
