Closes the window of this eWriter file (if called with a file name) or closes the viewer instance with all windows (if called without a file name)

Note:
Close is the only command that does note require a file name. However, you must still include the "?" query separator.

Note:
All examples are the argument. They must always be preceded by the eViewer app or the eWriter EXE file name if you are using that format on Windows. When using standalone Windows EXE files the file is both the viewer and the target and calls itself.

URL example eViewer app:
ewriter://<path+filename>?close
ewriter://?close

URL example Windows EXE eWriter file:

ewriter://<path+EXEfilename>?close
