Overview of the files in the project for Week 9


The project for this homework contains a number of classes. You have seen and worked with most of them.

Interfaces:
	IRange interface - we have seen for several weeks
	SortAlgorithms interface - used in the previous homework; represents a class 
                                   that can perform a specific sorting algorithm 
                                   on a specific data structure

Basic data class:
	City - represents the name, state, zip, latitude, and longitude
	similar to what you used for the last homework

Lists of data:
	AList, MTList, ConsList, ListRange - for traversals - used for several weeks

Java Power Framework - alternate edition:
	ActivityIcon, JPFalt, JPFApplicationAlt, JPFBaseAlt, MethodGUIalt - not to be touched,  
            but feel free to read

GUI for City input:
	CityView - GUI with text fields to input data for one City object, with submit and cancel buttons

Iterators for input and output:
	ListRange - to traverse an existing list of objects
	InConsoleRange - to read City object data from the JPT console - 
                         input ends when user hits return without entering any data
	InGUIRange - to read City object data from the CityView GUI
                     repeats until user hits Cancel
	InFileRangeBuffered - opens a data file and "generates" one object at a time.
              Note: it reads one line at a time from the file into a "buffer".

	OutFileRange - delivers one object at a time into the specified file

	IteratorRange - converts the Java Iterator into an IRange iterator, 
			so you can traverse any Java Collection without changing your code.

Comparators:
	NameComparator - to compare cities by lexicographical ordering of city names and states
	
	Your task is to implement a Comparator to compare cities by their zip code:
	ZipComparator

Sorting Algorithm Implementations:
	InsertListSorts - implements insertion sort algorithm on a AList data structure
	QuickListSort
	InsertVectorSort
	QuickVectorSort

Test class for the timer:
	TimerTest - contains the code that runs a suite of timer tests in succession.
                    the information about the needed tests is recorded in the following arrays:
                    sas - an array of instances of classes which implement SortAlgorithm
                    cmps - an array of instances of classes which implement the Comparator
                    datasets - an array of instances of lists of data to be used in tests
                    the results are printed to the JPT console

Test suite:
	TestSuite - contains tests for the input and output iterators 
                    and a sample of a test for the
                    InsertListSort with a timer test.

Input data:
	tencities.txt - contains ten cities for sample tests
	minicities.txt - contains about 20 cities for sample tests
	smallcities.txt - contains about 90 cities for sample tests	
        citiesdb.txt - conatins about 30000 cities for timing tests and stress tests
