Fourth Programming Assignment

	Write, compile, test, and debug a Java applet that uses the 
Swing user interface classes to provide the interface described below.
	The interface has a menu bar accross the top of the screen.  This 
menu bar has three pull-down menus:
1.  File containing New, Open, Save, and Quit options;
2.  Edit containing TypeFace, Size options;
3.  Help containing Version and Aid options.
What needs to be implemented for each of these options will be described 
later.
	Below the menu bar are two windows, side by side.  The left window
is one quarter the width of the right window.  The cursor starts in the
right window.  The right window is where the user enters text.  The left
window maintains a running total of the number of characters, number of 
words, number of sentences, and number of lines of text in the right 
window.  The right window can be scrolled vertically using a scroll bar
on its right.  

	New causes the right window to be blanked (have no contents 
except the cursor) and the left window to have all four running totals 
set back to 0.  Open brings up a box containing a list of text files in 
the current directory.  This box appears over the other two windows.  The 
user can employ the mouse to move the cursor to a particular text file
name and click the left mouse button to open that file into the right 
window.  The box disappears once the selection has been made.  When the
text file is copied to the right window, the left window counts are 
updated to reflect the text now in the right window.  Save brings up a 
box over the other two windows allowing the user to enter a file name 
under which the current contents of the right window are saved.  Quit
causes the program to terminate execution.
	TypeFace provides the user with a floating box containing a list 
of at least three type faces.  The user may select any of these type faces
using the mouse cursor.  Future text typed into the right window will now
be in this type face.  Size works in the same way except that it provides
at least three sizes for the future text in the right window.
	Version gives a one line message providing the name of the program,
its author, and version 1.0.  Aid is not fully implemented.  It brings up 
a single line indicating that help is not yet available.

	You should turn in a listing of the program that satisfies the 
Java programming conventions described elsewhere on this web page.  In 
addition, you should submit at least three screen images showing your 
program in execution with a variety of different situations.
