Get the extent of a route

Summary

There are two ways to get the extent of a route, one with a map and one without.

Procedure

• With a map:
  
  FindRoute with RouteFinderOptions.returnMap = True
  RouteInfo returns mapImageInfo, which will have an envelope object.
  
• Without a map:
  
  GetRoute with RouteFinderOptions.returnDirection = True ;
  and RouteFinderOptions.RouteOptions.returnGeometry = true ;
  RouteInfo will return segDescription and totalDescription.
  segDescription has an envelope for each segment, and totalDescription has an envelope for the total direction.
