BeginUpdate() public method

Begins a group of document changes.

Some events are suspended until EndUpdate is called, and the UndoStack will group all changes into a single action.

Calling BeginUpdate several times increments a counter, only after the appropriate number of EndUpdate calls the events resume their work.
