Print out station names.

stationstatus script will print station names. To be added is relevant
data about each station, and only print those station which contain
relevant information.
Use namespaces and find function to print all station names.

This is just a tidy up. Now uses find function instead of explicit
referencing of sub-elements (so robust to element order).
Also makes use of an abbreviation for the default namespace to save
typing and neaten code.
Report with details only on interesting station details.

Generates a report detailing the station name, status and message for
stations which have active status.
Train arrival prediction feed implemented.

Python script gets feed, writes to xml file, reads xml and writes
report to command line.
make_ script deals with reformatting xml file.
