Adding support for maneuver in the directions api.

[nutsiepully]

The directions API returns a useful element called maneuver which mentions the next action a traveler needs to take.

This commit adds support to parse that. It was pretty simple since the system does parsing internally based on the field names. I just needed to add the file name.

"steps" : [
                ...
                     "html_instructions" : "Turn \u003cb\u003eright\u003c/b\u003e onto \u003cb\u003eWightman St\u003c/b\u003e",
                     "maneuver" : "turn-right",
                     "polyline" : {
                        "points" : "w`yuFf{yfNn@?X?X?X?zBClEGxCAj@A~BG"
                     },
                     "travel_mode" : "DRIVING"
                     ....
                  }

Thanks,
Pulkit

See #49. This field is not documented, so we shouldn't really add it to the client without a @Deprecated header.

I'll merge this when we have a plan to address the other cases of this.

Have you signed the Google CLA?

oh - thanks for the PR!

@broady - Added the header. Already signed it. Thanks for the library! This saved me a lot of time 👍

This should be below, on maneuver. distance is a documented field.

Is this will be added to the library ?
