Document basic concepts

[Manu343726]

In addition to memory-specific concepts already described in docs, it would be useful to describe basic concepts of memory management, such as allocator, arena, pool, etc. This would make the library design easier to understand by newcomers. Also this clarifies the nomenclature used by the library and its docs.

Agree.
Dokumentation improvement is on my Todo-List.
Also plan to add groups, e.g. all allocator classes, adapters, etc. for easier overview.

It would also be very helpful, to have an more complex example where we build something
like the complex composed allocator Andrei Alexandrescu showed in the video: https://youtu.be/LIb3L4vKZ7U?t=4125

I am also wondering if there is already some allocator in the library which splits to different allocators depending on which core (thread) it allocates... (?)...

I have the segregators: https://foonathan.net/memory/segregator_8hpp.html

No, there is nothing like that, but PRs are welcome.
