Homework COSC 231
Distributed:  13 April 2015       Due: 20 April 2015

Write a multi-threaded Gui app in Java using javax.swing.Timer. 

There will be a main thread that starts the Java GUI.

This application will be a tool to improve reading speed. There will be a slider
input that controls the display of individual words in varying words/minute (wpm). 
The slider will control display from 50 wpm to 500 wpm.

Individual words from a text file will be displayed on the GUI at the rate given
by the slider. The rate can change dynamically -- the input file does not have
to be read all the way through, neither is the user required to stop the
word display in order to change the rate of display.

Individual words can be displayed in a textfield, textarea, or other appropriate
output component.

The user is also given a control to change the font size of the displayed word.
This should be in the form of labelled radio buttons with font sizes: 12, 14, 18.

The user is also given a button to start the display.
The user is given a button to stop the display.

GUI components:
  slider for wpm
  button: start display
  button: stop display
  radio buttons: font size
  output component: word.

The input file can be hard-coded for this homework.

The window control buttons must work properly. The window must have a title.

Turn in:
Hard copy of source code
Screen shot
Demo and code walk thru.

Grading based on:
Meets specs
GUI look
Code readability
Code elegance
