OpenLayers KML Track in a PointTrack Layer Example

# Parsing gx:Track in KML

Demonstrates populating a PointTrack layer with gx:Track elements from KML.

If a KML document contains `<gx:Track>` elements and the extractTracks property is set true on the parser, features will be created that represent track points. These track points can easily be visualized as track lines with a `PointTrack` layer, preserving the KML's original styles.

View the kml-pointtrack.js source to see how this is done.
