		// hard coding a filename into a program is evil.
	   // alter your program so that it gets the correct filename from the user.
		
		
		
		// check that your program works when you give it the correct filename
		
		
      // now type in an incorrect filename. What error message is output
		// by your try/catch block?
		
		
		
		// alter your try catch block so that instead of quitting, your
		// program tries again until the desired filename is entered.		

Part 2
				
		// now copy the file numbers.txt to your working directory 
		// the file was supposed to contain only ints but professors
		// Harris and Adams were tired when they created it so it has
		// some junk in it.  You must deal with the file as it exists.
	   
		// this part of the lab asks you to actually process the data
		// in the following way.  Note that may only read the file data once.
		// You are to:
		//   find the smallest int in the file
		//   determine whether the value  13 is in the file and print
		//   a message telling how many times it occurs.
