Ability to get the lat max/min, lon max/min

[Qwertie-]

Would be useful if this library let you get the maximum and minimum values for longitude and latitude. Use case being you would be able to draw a box on a map that fits the whole gpx file inside of it.

This is resolved. The bounds method on GPXFile will return GPX::Bounds, with min_lat, min_lon, min_lat, max_lon attributes.
