/** The controlling process for an application. 

An instance of this class is created by the Uikon environment. This instance 
calls CApaProcess::AddNewDocumentL() to load the application DLL and 
construct the new application which runs in this environment. 

It also provides services related to an application's main (non-embedded) document, 
including: 
- saving the main document to a direct file store
- providing the name of the most recently accessed file
- getting the name of the application DLL associated with a document.
