1. Some docs 2. Basic tests for ResNet and ResNeXt now pass
1. Less keywords for the user to worry about 2. Delete `ResNeXt` just for now
`downsample_args` is actually redundant
Also add tests. A lot of tests
Also 1. Tweaks - II : Formatting + some docs 2. Groundwork for abstracting out the classifier
1. Reorganise layer imports for easy access 2. Get pooling to work
So much GC, might as well have a function for it
Co-authored-by: Brian Chen <ToucheSir@users.noreply.github.com>
Neither does formatting, unfortunately. Also refactor `classifier` to separate out FC-layer creation and pooling
It really does never stop Co-Authored-By: Kyle Daruwalla <daruwalla.k.public@icloud.com>
And make `downsample_opts` a smidge easier to work with. Also, a wee bit o' formatting and cleanup.

Closures is the name of the game
Simplify `conv_bn` to `conv_norm` and use it
And some more formatting
Also 1. Make class tokens optional 2. Allow class tokens to be before positional embedding as in DeIT-III

what's status now ? |

I've had less time to work on this in the recent past, but I'm going to try and push some of these refactors through in the next few months. However, there's some work that's also happening on the Attention implementations around the Flux ecosystem - I suspect any reforms to the ViT will wait on that work to land |

This modifies the current ViT API to add more options - notably, there is now a optional
prenorm/postnormtoggle. There's also an option to make class tokens disappear completely, and also to allow class tokens to be before the positional embedding as in DeIT-III. This makes some other cleanup changes as well. The API is more congested for now but I thought I'd get this in before I start working on the other ViTs - maybe there's some potential for extracting common stuff out there.Needs #174 to land before this makes sense. Also documentation is pending
