Group actors into groups and remove them en masse

@acxsasx

I do not mean to offend, but this is a basic concept in programming with C++.

I have not used TMultMap. Beware that some of these containers may not be supported in Blueprints.

No offense taken, I am new at C++ and I dont intend to use Blueprints.

@STRiFE.x

I’d like to mention that mass deleting actors will cause an fps stutter (probably a big one) if you are doing it from the main thread.

And is there a way to do it without significant performance drop? Or do I have to learn multi-threading? I am definitelly going to do multi-threading, but it seems like high-level stuff to learn so I have not yet touched that concept.
