[Maposmatic-dev] [PATCH 02/22] coords: add BoundingBox::as_javascript() method

[Thomas Petazzoni]

This method returns a string containing a bit of Javascript code that
is useful to render the Bounding Box with the Leaflet Javascript
code. It allows to quickly have a graphical representation of multiple
bounding boxes on a slippy map. This is very useful to understand if
the computations done on bounding boxes are correct.
