   Assignment:	Project 1
   Due Date:	February 6, 2003
   Description:	The following program reads the contents (a list of states
		and their attributes) of a file (States.data.txt), sorts
		the information alphabetically by the state's name, and
		prompts the user to search for a state.  If the user's 
		searchterm is found the state's name and its attribute's 
		are output to both the screen and a file names statelog.txt.
		Otherwise, a "contents not found" message if output to
		both the screen and the afore mentioned file.
