Extended RailNet example as Sinatra web app

[Bert Fitié]

Hi,

I extended the old RailNet example of the Neo4j.rb distribution and
implemented it in Sinatra as a web app.

To give an idea of its functionality I include below a few "screens"
with their URL. Path symbols and node id's in these screens are
between [square brackets] and are hypertext links.

(@Andreas Ronge: if you want to include the updated example also in
the examples folder I can send you the source zip file off-list)
