"Hello world" example of a single-file 'library'.

After importing this file, you can then use this file to mock submodules for
a library. For example,

    import main  # this file
    import torch.nn.functional  # 'imports' the mock module below instead

This helps with debugging, logging, and more.

We need this when there are multiple classes inheriting from each other. Here's an example: Say we have classes A, B and C. Define B and C, so that there are no parent classes:
