since Queue is a common data structure, put it in a special dir from arduino mocks to avoid conflicts

+The parent directory is for files that must stand in for their Arduino counterparts -- any `SomeFile` that might be requested as `#include <SomeFile.h>`.
+
+This directory is specificially for support files required by those other files.  That's because we don't want to create collisions on filenames for common data structures like Queue.
+
+If there end up being class-level conflicts, it is this developer's stated intention to rename our classes such that `class Float` becomes `class FloatyMcFloatFace`.
