Shuotian and Joshua Iteration 4 Commit
Refactoring:
Attempt to apply OOP principles to Javascript functions.
Compressed Facebook API calls and related friends list functions into a single facebookFriends object, reducing dependency on global variables and improving code organization.
Unable to add Facebook initialization functions to facebookFriends object because it has to be called before we create a new facebookFriends object.
list.js is now unnecessary, the function has been collapsed into the new object.
