bool	ProcessRequirements ()
	Process additional requirements before the directory fetch is performed. Some directory fetches may require authentication, keyboard input etc. The IDirectory subclass should call GetKeyboardInput, SetErrorDialog or RequireAuthentication and then return false from the GetDirectory method.

Protected Member Functions
bool	GetKeyboardInput (const CVariant &heading, std::string &input, bool hiddenInput=false)
	Prompt the user for some keyboard input Call this method from the GetDirectory method to retrieve additional input from the user. If this function returns false then no input has been received, and the GetDirectory call should return false.

	Show an error dialog on failure of GetDirectory call Call this method from the GetDirectory method to set an error message to be shown to the user.
