+        - The top of the file after the includes, put a nice /* */ section
+          which gives a high level overview of how the implementation works.
+        - Single line // comments are to be used sparingly and judiciously
+          which explain the why (not the what or how) when it is non-obvious.
+        - Docstrings are required for all classes in public headers in
+          non detail namespaces. They are used for generating the Documentation
+          website. Please give warnings for any class or function that does
+          not have a docstring or has an insufficient docstring.
