This is used for store data as elements and treat them with indices in maximized speed.
Subtraction of middle-indexed element will not cause pushing of backward elements. Specified index of an element will remain until Sub() is called.
-Technical Time Complexity-
Get() : If TotalBufferAllocated < Capacity Then 1(with existing bit check, 2),
else, log capacity ElementCount (the higher capacity, the extremely faster access speed)
Add() : 1(always finds empty index at once). with setting existing bit, 2.
