ViewManager (apache-cassandra API)

```
public class ViewManager
extends java.lang.Object
```
Manages View's for a single ColumnFamilyStore. All of the views for that table are created when this manager is initialized. The main purposes of the manager are to provide a single location for updates to be vetted to see whether they update any views updatesAffectView(Collection, boolean), provide locks to prevent multiple updates from creating incoherent updates in the view acquireLockFor(int), and to affect change on the view. TODO: I think we can get rid of that class. For addition/removal of view by names, we could move it Keyspace. And we not sure it's even worth keeping viewsByName as none of the related operation are performance sensitive so we could find the view by iterating over the CFStore.viewManager directly. For the lock, it could move to Keyspace too, but I don't remmenber why it has to be at the keyspace level and if it can be at the table level, maybe that's where it should be.
