Const' declared instances of Vtr::Array do not protect the pointer held privately by the class properly. In order to force the compiler to protect this pointer, we removed all non-const accessors from Vtr::Array (now renamed Vtr::ConstArray) and moved them to a child class (Vtr::Array), which requires const_cast<> operators internally to allow access. The change & renaming is then propagated to all internal dependencies.
