Added some methods related to NoF verification in the ManagerController.
Created the NetworkOfFavors and Member classes.
Only method signatures were added to the new created methods...
In createInstanceForRemoteMember we added some lines to call methods of
NoF. These methods verify the reputations of the requester member and
the members already using local resources in order to perform the
resource deallocation of members with lower reputations to free
resources to the requester.
These methods are in form of contract/signatures (no code in body).

We started to set up the "Accounting Updater" on manager. There are
still some issues to fix.
All methods are in form of signatures (no code in body).

In createInstanceForRemoteMember we call some methods of NoF. These
methods verify the reputations of the requester member and the members
already using local resources in order to perform the resource
deallocation of members with lower reputations to free resources to the
requester.

We also set up the "Accounting Updater" on manager based on ManagerTimer
class.
Everytime this method is called, NoF performs the following updates:
1 - updates reputations of members;
2 - updates the values of fairness and satisfaction of local cloud;
3 - updates the amount of resources supplied to the federation.
