+//  LinkedBuffer.hpp
+//  Lock-free (except when linking atm) buffer which propagates its changes to linked buffers
+//  All linked buffers can be in different threads (read: should be)
+//  Requires an update function to be called in the thread which it resides in
+//  Concurrent sets must be ordered to have synchronized operations, accumulation can be nonsync

+/*
+ TODOS:
+ - Cache line optimization!!!
+ - Write own underlying allocator so ( AUTO ) resizing can be lock-free
+ - !!!!! Add iterators ( But not the c++17 deprecated one )
+ - ACCUMULATOR!! ( This and certain operations can be concurrent without passing a + b, just + and b)
+ - Make linking lock-free
+ - Check for feedback loops when linking and throw error / return false if thats the case
+ - !! Add more instructions, such as:
+    -  Curves?
+    - !Summing
+    - !Checksum sharing
+    - Function?
+    - Make something useful of double operator setter? < Test new implementation
+    - Resizing!
+    - Allow different sized buffers with relative - interpolated - sets?
+ 
+  allow all integer and float types in subscript operator
