Display direction on transfers in route details actiivty

[GoogleCodeExporter]

Description:

After I plan a route, there is the button to show it in text format
(words, rather than the route map).

Using a short trip in Beijing as the example (since I was just there,
using your app, and found I really needed this feature!) it may show:

Chongwenmen
5

Dongdan
5

Dongdan
1

Wangfujing
1


It would be nice if when you are getting on a train, it tells you
which way to go on that line -- most subway systems show this on their
signs by naming the stations at the end.  So it could show something
like this:

Chongwenmen
5 (direction: Tiantongyuan North)

Dongdan
5

Dongdan
1 (direction: Pingguoyuan)

Wangfujing
1
