Pytorch, Ignite, Monai -> Monai Label Tutorial

[danieltudosiu]

Is your feature request related to a problem? Please describe. Due to the complexities required by the creation of interfaces for the backend and frontend to interact the "information" flow within MONAI Label is heavily offuscated and hard to comprehend for development.

Describe the solution you'd like Create the following four animations/figures:

• An UML-like figure of MONAI Label that is specific for the backend to complement the existing REST API one.
• Three transition animations that exemplify how you move from X to MONAI Label, where X is:
  • Pure Pytorch
  • Ignite
  • MONAI

The last point is inspired by the PyTorch Lighting animation which conveys a lot of information in a very succinct way.

Additional context This came to be after I had explained MONAI Label to @MichelaA and a while ago Ignite to @diazandr3s. This would facilitate a faster and better understanding of MONAI Label and hopefully as a side-effect less issue.

Furthermore, this falls in line with the style of tutorials that are available in MONAI Core and it would be highly useful due to the fact that MONAI Label borrows design from PyTorch Lighting ultimately merging two very different APIs together which leads to a steep learning curve.
