THnSparseArrayChunk is used internally by THnSparse.

THnSparse stores its (dynamic size) array of bin coordinates and their contents (and possibly errors) in a TObjArray of THnSparseArrayChunk. Each of the chunks holds an array of THnSparseCompactBinCoord and the content (a TArray*), which is created outside (by the templated derived classes of THnSparse) and passed in at construction time.
