Implements a panel that allows the user to save a file.
There is only one save panel per application and this panel is obtained by calling the +savePanel class method. From here, you should set the required file extension using -setRequiredFileType: When ready to show the panel, use the -runModal, or a similar method to show the panel in a modal session. Other methods allow you to set the initial directory and initially choosen file. The method will return one of NSOKButton or NSCancelButton depending on which button the user pressed.
Use the -filename method to retrieve the name of the file the user choose.
