Investigate options for bulk data export about beehive-server HOT 3 CLOSED

Since I was a little concerned about making sure we're able to do this for backups ASAP, I went ahead and added two tools to:

https://github.com/waggle-sensor/beehive-server/tree/master/data-exporter

export exports all the datasets from a specific node
exportall exports all the datasets

These export datasets to CSV files in data/*node_id*/*date*.csv.

(These will end up as one tool...I just wrote export as a quick prototype.)

from beehive-server.

That was faster than I expected! Doing a full export this way took about 15 minutes. We just need a good place to keep the data. It's just under 5 GB uncompressed, so space isn't really an issue.

As another data point, exporting all of the new Panasonic node's data took about 7 seconds.
