Better name for Stack

[Wasabi375]

I have renamed stak to Stack because I got annoyed by the wrong spelling. I also changed it to upper case to follow kotlin coding conventions.
The problem with this, as @elect86 pointed out, is that this might conflict with java.util.Stack which is a LIFO Vector implementation.

The question is, should we change the name of Stack again so that we no longer have an conflict? I'm personally not sure how often people use java.util.Stack anyways and then how often this would come in conflict with ours. This issue is to keep track of the problem

I happened to use java Stak only in imgui, but I do admit it's quite rare to see it

One alternative might be stacked
