These methods create and return a document and load a project file into it. The argument must be a string pointing to an existing file. If the file doesn't exist or the file cannot be loaded an I/O exception is thrown. In this case the created document is kept, but will be empty. If is used, the document won't be displayed in the GUI and no tab will appear for it. This allows performing automatic operations on a document and closing it without disrupting the user interface.
