Find By Id Performance Enhancement with Map

[dhdnjswnd]

I draw large amount of objects which is more than 50,000.
And I also try to edit them interactively.
I found out it is really slow when I'm looking for a specific element.
(Plz let me know if you have another way to search an element)
(I cached groups to improve performance.)

It is caused by the way Container handle their children.
They find an element in DFS way.

How about handling children in two ways?

Of course, I should change all functions, like remove, add, delete.

`export abstract class Container<
ChildType extends Node = Node

extends Node {
children: Array = [];
/// plus mappedChildren: Map<String, ChildType> = new Map<String, ChildType>();
`

Did you try to run profiler? What exactly is slow? Rendering? Search by id? Something else?
