ElevationProfile widget - user-specified input geometry

Description

This sample allows input of either a polyline or freehand polyline geometry. The elevation profile is based off of this geometry and is calculated using the elevation profile service specified in the profileTaskUrl. There is also the option to change the unit of measurement.
