tree.intersects(bbox)

RBush is often used for collisions, so lets make a method that does the same as search but without collecting/returning items, just true/false.

In the ol3 port RBush, the traversal takes a callback which allows you to break out of the traversal by returning a truthy value. This can be used in many ways, for example:

// return true if any feature is at the coordinate
var coordinate = [x, y];
var anyFeatureAtCoordinate = rBush.forEachInExtent(extent, function(feature) {
  return feature.getGeometry().containsCoordinate(coordinate);
});

// find first feature only
var firstFeatureFound = rBush.forEachInExtent(extent, function(feature) {
  return feature;
});

@twpayne that's pretty neat. I'll think about this.
