/*
* This is where the implementation of the DBus based document API lives.
* All the methods in here (except in the helper section) are
* designed to be called remotly via DBus. application-interface.cpp
* has the methods used to connect to the bus and get a document instance.
*
* Documentation for these methods is in document-interface.xml
* which is the "gold standard" as to how the interface should work.
