/**
*
* EGMapKMLLineString Class
*
* KML LineString tag object
*
* Defines a connected set of line segments. Use <LineStyle> to specify the color, color mode, and width
* of the line. When a LineString is extruded, the line is extended to the ground, forming a polygon that
* looks somewhat like a wall or fence. For extruded LineStrings, the line itself uses the current LineStyle,
* and the extrusion uses the current PolyStyle.
