// Marty Stepp, CSE 142, Autumn 2008
// This program reads a file containing the IMDb top 250 all-time movies
// and displays all movies matching a search phrase.
//
// This is a bad version of the program, which uses "chaining."
// Chaining is when each method just calls the next one, never returning to main.
//
// Look at how the methods in this program just end by calling the next method,
// and how they increasingly accept more and more parameters, but never return.
// Also notice how main becomes just a single line, a single call.
//
// The program works, but all of this is bad style.
// The main method should be a concise summary of the program.
