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.

You can use the Kite CLI or Hue to view records.

If we mention that the files aren't human readable, then we should explain that they are stored in efficient binary formats that are designed to work well in Hadoop.
