AHELP for CIAO 4.15 Sherpa
Start the image viewer.
The image viewer will be started, if found. Calling this function when the viewer has already been started will not cause a second viewer to be started. The image viewer will be started automatically by any of the commands like `image_data` .
Image visualization is optional, and provided by the DS9 application.
