==== Lab 2: Using Javadoc ====

  * Use the code in chapter 1 as your starting point for a Greeter program. 
  * Create the program in a subdirectory of your CS203 directory called Greeter.
  * Add Javadoc comments to the Greeter Class and the main method. 
  * Any other classes or methods you create in this project should have Javadoc comments.
  * Generate the Javadocs. There are several ways to generate the javadocs:
    * Right click on the project name and select "Generate Javadoc"
    * Click on Run and select "Generate Javadoc"
  * You can then see your Javadocs in a browser by right clicking on a class and choosing "Show Javadoc".
  * Add a setName method to the Greeter class. 
  * Create a class GreeterApp with a main() method for testing your program.
  * In main(), create two Greeter variables that refer to the same Greeter object. Invoke setName on one of the references and sayHello on the other.
  * Write a method void swapNames(Greeter other) of the Greeter class that swaps the names of this greeter and another. 
  * Exercise swapNames in main and show that it works.
  * Save your projects on github in your local repository and your Vassar private repository. 
    * Remember to save your work to your local repository first. 
    * Remember to be in your cs203 directory when you issue your github commands 
  * Once you have saved your work in your local repository do a remote save to your private github repository which has been created for you.
  * Your private repository has been created within an account called Vassar-cs203. 
  * Your github address should look like https://github.com/Vassar-cs203/yourVassarEmailName.git.
    * Refer to Lab 1 for the github commands. You will be starting with the "git add ." command.
