示例1: kml2wkt
/**
* kml2wkt does what its name implies :
* it takes a kml file, parses it for linestrings and returns an equivalent WKT LINESTRING
*
* The returned WKT can be 2, 3 or 4D.
* If does not really handle 4D parsing (beyond scope IMO) => KML import is restricted to routes (outings will only support GPX input)
* If $dim = 4, then time field will be zero-padded.
