      public int compareTo(ModuleVersionNumber installingVersion)
      Now that we create internal releases of the form M.m.r-M9 (milestone), M.m.r-A9 (alpha) and M.m.r-RC9 (release candidate) during development and testing, we need to ensure we can upgrade from any of these to any other, as they may occur in any order and also to the final external release M.m.r. We also will allow a change from the final release back to an internal one for regression testing. The code within ModuleComponentHelper which calls this method, checks if it is the same version (0) and then if it is downgrading (> 0), so if they share the same M.m.r part matches AND is one of these formats, we return <0.
      Parameters:
      installingVersion - the new version
      Returns:
      a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
