Moving Kite Dataset API info from old guide per CDK-753.

Link to the old guide from which this came. This is just shards of information brought forward so they're not lost. This info should be woven into the samples before 1.0.

Because view is not defined at this point and the docs aren't available to link to, I think it should be "views of a dataset" instead of just "views".
