Add option to put number of data centers

[otrebski]

Cassandra can be configured to have for example cluster of 9 nodes divided into 3 data centres. Can you provide such option to calculator?

That would get a bit complicated visually I think, since the DCs can have different Replication Factors. If anyone can think of a good way...?

I think this is a great suggestion! We could add a drop down to specify the number of data centers and then dynamically add fields based on those values to specify the replication factor of each region. I guess in most scenarios, all data centers will have the same replication factor. Thanks!
