Log Message:
-----------
1 Add the protocol and the classes related to log propagation. Also add a simple implementation in the withlog package and a test case TestSimpleDbWithLog.
2 Add the RangedDatabase class which contains NodeStatus, Database and Log.
3 Add "getDocs" to the Database class to retrieve a number of documents. This will be used to improve performance during the log propagation. Q: Should Database be aware of Range to support filtered queries based on Range? Or do we make RangedDatabase add a clause to a query before passing it down to Database?
