	StringList - by Jeff Martin

	StringList (a subclass of Storage) is a convenient way to deal with lists of character strings. It contains methods for adding strings, inserting strings, sorting strings and searching for strings.
		
	StringList can also add strings from a delimited string (such as the ones passed to an app by the workspace). The delimiters can be supplied or assumed to be white space.
	
	Finally, StringList implements a browser delegate method so that it can easily display itself if set to be a browser delegate.

	To use this object inside of InterfaceBuilder, simply drag its icon from the palettes window into the suitcases window. Then drag in a browser and set its delegate to be the stringlist. Type in some entries into StringList's inspector and test interface. The browser fills up!
