Class structure for Nested Steps

[Turan]

When in transit mode some responses will contain Steps within Steps s there is a need for DirectionStep to contain an instance of itself.

[Eric Newton]

Ok, sounds reasonable. Can you provide a specific example of a response that returns this situation? Post it here to add to the knowledge of the issue itself

[Turan]

Sure for example doing the query:

https://maps.googleapis.com/maps/api/directions/json?origin=oxford%street+london+UK&destination=bond%street+london+UK&mode=transit&key="REMOVED"

Will return steps that themselves contain steps, looking at the extract below steps contains another array called steps with a slightly different make up:
