Big Java example project "pipes"

You can use this project as follows:

 - invoke the main method of the driver classes Split & Unique by right-clicking 
 on the class representation and selecting the main method.
 - you will need to open the BlueJ terminal window to input values
 - each time you hit enter any words input will be processed either by 
  tokenizing (Split class) or filtering repeated content (Unique).
 
Note: Due to BlueJ's current input handling implementation it is necessary
 to reset BlueJ's Debugger Virtual Machine to halt reading input.  
 Right-click on colored work indicator (aka barber's pole) 
 and select Reset Machine. 
  
This project illustrates concepts covered in Big Java, Chapter 6 
"Iteration".
  
 - to be able to program loops with the while, for, and do statements
 - to avoid infinite loops and off-by-one errors
 - to understand nested loops
 - to learn how to process input
