Return triples in the bounding box specified by X-min, Y-min, X-max and Y-max.
This can return the subject of the matching triples or the subject and the coordinate (which is in the object). For example:
  ?event geo:inBoundingBoxXY (ex:locationPredicate 1.0 2.0 4.0 5.0) .   or
  (?event ?coord) geo:inBoundingBoxXY (ex:locationPredicate 1.0 2.0 4.0 5.0) .   The four locations specifying the box must all be bound before this magic property can be evaluated.
