- apparently needed to specialize a templated sub-class of a template
  class
  Normal:
      template<>
      defineDebugSwitchWithName(Type, Name, DebugSwitch)
  New for sub-classes:
      template<>
      template<>
      defineDebugSwitchWithName(Type, Name, DebugSwitch)

- duplicates existing SubField -> Field conversion method
- retain for Intel until we confirm it works there too

- specializing within deeper nested namespaces is not allowed
