/* new user: creates an account. Ask for a username and password //readline(), getUserName(), getPassword()
	  then signs in.
	  new user starts at Harris for New Student Orientation.
registered user: signs in.
Check the world to see what room the user was in the last time. [String getLastLocation(String username)]
Call the user's stats and inform the user how many turns he/she has left. [int getUserStats(String username)], [int getUserTurns(String username)] 
The user is asked where he wants to go (South Campus, North Campus, East Campus). [pickCampus()]
The event manager is called and the user is informed of the options of buildings and events. [Array listBuildings()]
The user picks a building [void pickBuilding()] 
The user chooses a room. [void pickRoom()]
Give a description of items in the room.  [Array describeItems(String room)]
If there are fewer than 20 other users in the room [int getNumberOfUsers(String room)], the user goes into the selected room. 
Otherwise the user must choose another room. [void pickAnotherRoom()]
A list of objects is given to the user as well as the actions that he can perform (talk, learn from professor, drink, etc.) [Array describeObjects(String room)]
The user begins to pick objects. [void pickItem(String username)]
We keep track of the items picked up. [void recordItems(String username)]
We then update the user's stats. Certain objects have more value than others(determined by World) [void setStats(String username)]
If the user tries to pick up too many objects, or goes beyond the size limit, he is informed that his backpack is full. [println("No more room in your backpack. Discard an item.")] 
User keeps performing actions like bodybuilding, resting, learning, and drinking until he runs out of turns for the day or he decides to log out. 
 
 
 a. interactWith:
	Advantages
	  * less typing
	  * less work for the world (possibly overburdened)
	Disadvantages
	  * the commands are less centralized
   interact:
   	Advantages
	  * centralized commands
   Decision: use interact(String actor, String verb, String target)
   
b.  Use objects. It's easier to not have to worry about the string.
 
c. 
 World
	  * boolean signIn(String username, String password) -if username matches with password, sign in user
	  * boolean isValid(String username, String password)
	        username = getUserName() // getUserName involves readline()
 	        password = getPassword() // getPassword involves readline()
	  * String getLastLocation(String username)
	  * int getUserStats(String username)
	  * int getUserTurns(String username) 
	  * Array listBuildings()
	  * void pickBuilding()
	  * void moveToRoom(String room)	
	  * void interact(String actor, String verb, String target)
	  * boolean isCapable(String actor, String verb)
 
 Place 
  	* void pickRoom()
	* int getNumberOfUsers(String room)
 	* Array listObjects(String room) 
	* void pickUpItem(String item)
 	* void recordStatOfObject(String room) // record these in an array
  	* void removeObject(String item) 
 
 Person
 	  * void addToInventory(String item)
	  * void increasedSkill(String skillcategory, int numincrease)
	  * void useItem(String item, String target)

  Thing
 	  * String describeMyself(String item)
	  * boolean useableItem(String item, String verb)
	  
d. When interacting, the world informs the target that a user has performed an action on the person.
