find_distances: initial script to find rail stations with distance to London etc
CSV file with all UK railway stations and their 3-letter codes; from National Rail website
first result of search for stations 50km radius around London
national_rail_results.html: example Website result for URL query http://ojp.nationalrail.co.uk/service/timesandfares/MOT/SE11PP/tomorrow/0900/dep
Explanation for custom URL creation:
MOT = Motspur Park
SE11PP = d3 address post code
tomorrow = date [TODO: exact accepted format!]
0900 = time
dep = departure or arrival
find_distances: refactor to be easier to configure; load/query stations for d3 and MBH address
find_distances: create filenames from input parameters
TODO: make params settable from cmdline
find_distances: add merge code for stations; TODO: implement comparison/equality operator,
 so that it actually works
find_distances: add some __eq__ operators

find_distances: fix list should be extended (append all list items, rather than append list itself)
find_distances: fix merge. TODO: makes this more pythonic, cannot be bothered to do it better while coding on a train
find_distances: load all data fields from file, incl. triples of distance data
find_distances: fix merge adding place0 twice by checking for existence of place name;
TODO: does set() need __cmp__ defined?
add some doc.

find_distances: add "mode" with default value "driving", see gmaps API doc:
  https://developers.google.com/maps/documentation/directions/#TravelModes
test batch script so I don't need to type Python path all the time
find_distances: move global gmaps object to top, so it's created upon import
find_distances: explicitly set mode for gmaps query, add doc link
test script to check for kwargs in gmaps query
find_distances: mark global vars by g_ prefix
find_distances: try to add mode="transit" and departure_time according to gmaps API doc.
Add global default departure time "now".
Note: doesn't seem to work, still gives driving results...
find_distances: log warnings and errors to stderr
find_distances: log newline for faster finding of new logs
