Attempt to scale and centre the map based on bounding box size

This is an intermediate commit so I can recall a lot of code that is about to be deleted
as it seems that using the map.setCenter method will achieve what we want but there is
some code here that could be useful to recall if we decide that the bounding box should
determine the size of the extent.
Centre and scale search results map on metadata bounding box

Use the centre of the bounding box from the metadata and call the map.setCentre method with
a zoom level to size the map.
