/* This struct holds private data for the cbEditor class.
 * It's a paradigm to avoid rebuilding the entire project (as cbEditor is a basic dependency)
 * for just adding a private var or method.
 * What happens is that we 've declared a cbEditorInternalData* private member in cbEditor
 * and define it in the .cpp file (here). Effectively, this means that we can now add/remove
 * elements from cbEditorInternalData without needing to rebuild the project :)
 * The cbEditor::m_pData is the variable to use in code. It's the very first thing
 * constructed and the very last destructed.
 *
 * So, if we want to add a new private member in cbEditor, we add it here instead
 * and access it with m_pData->
 * e.g. m_pData->lastPosForCodeCompletion
 * and of course you can add member functions here ;)
 *
 * cbEditorInternalData also contains a pointer to the owner cbEditor (named m_pOwner).
 * Using m_pOwner the struct's member functions can access cbEditor functions
 * (even private ones - it's a friend).
 *
 * The same logic should be used all around the project's classes, gradually.
