/**
  * VC++ can't export/import classes easily, so we build the sdk as a lib. However, singleton
  * managers should be in a DLL to be shared across "src" and all plugins. So, we do the
  * following for static lib SDK builds:
  * Define an instance of every (singleton) manager in a "CodeBlocksManagers.dll". The
  * manager classes use those instances instead of local ones.
  *
  * We define accessor functions (GetManager/SetManager) to the manager instance for both
  * implementations (static and dynamic lib SDK)
  *
  * @todo Perhaps use an overloaded assignment operator instead of "Set"
