Add output formatting options

[powersa]

If possible, allow users to select how they wish to export bbox coordinates. For example if bbox is used in SQL query, usage format would be something like:

SELECT * FROM logs WHERE lat > 47.1152542 AND lat < 48.0326795 AND lng > -122.6954903 AND lng < -121.937685;

Would be interested to hear how other people use bboxes and if steps can be saved through formatting.
