/*
 Use a preprocessor macro in build settings to define
 
 V002_UNIQUE_CLASS_NAME_PREFIX=MyPrefix
 
 Alternatively define
 
 V002_CLASS_NAMES_PRODUCT_IS_APP
 
 to use straight class names for app code ONLY.
 ALWAYS use the prefix when building loadable code (eg plugin, bundle).
 
 The rest, including class aliases, will happen automatically
