/**
 * Feedback from Alex This class is a work in progress, we still need to take
 * care of file input and output. Since we are printing our contacts in a table,
 * we must also print column names in main In the future I think this Tester
 * class should have some other static methods that each take care of a specific
 * job such as printing, scanning, or reading. That way the main method doesn't
 * look so clutered. Also, lets rename the class from Tester to TestContactList
 * or something
 **/

/**
 * Feedback from Adina Change the name of the class so that it matches the name
 * of the .java file. Or, as Alex said, it would be even better to call the file
 * TestMyContactList.java and call class TestMyContactList. I believe this would
 * be more descriptive. Write JavaDoc format comments above this class that
 * should start "This class tests..." Create an object of EACH class (both class
 * Contact and class MyContactList) and call EACH method on these objects. COPY
 * AND PASTE recording of run. /
 * 
 * /** Feedback from Gabe to Adina on TestMyContactList Make Scanner private;
 * More descriptive object name; I liked what you did when asking for last name,
 * but i think the guideline wants us to just not add the contact if the last
 * name wasn't entered. Maybe add it as a helper method and use it if allowed?;
 * To both Alex + Adina: Does the use of the promptUser() method + the
 * addContact(Contact person) makes the use of newContact(...) essentially
 * useless? Should we get rid of newContact(...); on Contact() Instead of
 * Assignments onthe constructor why don't we just call the setters thus
 * minimizing code? Do we need that many tabs?
 **/
 
 /**
  * Feedback fro Adina to Alex:
  * Output does not match UI design, 
  * 1)the first line should say "-------------Print Contact List------------" 
  * 2)UI has ONE space(\n) above each printed contact, programs output does not have any before the first contact and has two between 
  * following contacts.
  * 3)When list is printed, program does not have "Press Enter to return to main prompt: " as UI design does.
  * 4)Also, Ui design and program output have different number of spaces between printed info. For exapmle, 
  * "First Name:	Howard" in program output lacks spaces
  * 
  * I tested the implementation of case 2 on my system and run I got is: 
  * 
  * __All Contacts__
