Kml Reader

The program extract information from the KML file by parsing the words
LineString  and coordinates. Usually there is ONLY ONE section for coordinates.
If this is the case the list sections will not be shown.
However if there are more then one section a list of all the sections will be shown.
And the map will show the first section.
Further more if no height data is included , the list will be empty and the graph will not
show any data.
