Updated comments and deleted surplus commented code.
Outsourced the main method of ContactManagerImpl class to this new class to handle the running of the program. This shortens ContactManagerImpl considerably, making it easier to navigate.
Removed surplus comments. Also added a getContactList() method so that the ContactManagerRunner class can access the contactList field of ContactManagerImpl, which needs to be passed to ContactManagerUtilities occasionally.
Removed commented code.
Removed commented code and duplicate comments.
