CORE
====================================================================================

Use <code lang=C++>SFWCore::setup();</code> to initialize the library.
This is necessary as some components (Like PoolVector, and StringNames.) need additional setup.

Use <code lang=C++>SFWCore::cleanup();</code> to de-initialize the library.

Note that if you use the Application class, it's constructor will do this for you automatically.

Also note that if you don't use classes that doens't rely on this you can get away by not calling it.
