+/// This provides a very simple, boring adaptor for a begin and end iterator
+/// into a range type. This should be used to build range views that work well
+/// with range based for loops and range based constructors.
+///
+/// Note that code here follows more standards-based coding conventions as it
+/// is mirroring proposed interfaces for standardization.
