Get all coordinates from any GeoJSON object.

@name coordAll
@param {FeatureCollection|Feature|Geometry} geojson any GeoJSON object
@returns {Array<Array<number>>} coordinate position array
@example
var features = turf.featureCollection([
  turf.point([26, 37], {foo: 'bar'}),
  turf.point([36, 53], {hello: 'world'})
]);

var coords = turf.coordAll(features);
//= [[26, 37], [36, 53]]
