Write a Scala library for parsing dates #59

There are lots of different date formats in the Calm data – the Calm docs list the supported formats, and there are plenty more extra “features” that we’ve introduced.

We need to be able to parse these strings and turn them into a canonical representation.

Some possible thoughts on how we might do this:

Elasticsearch 5.2 supports date range fields, so we could use this to store ranges.
I’ve done a bit of work with pyparsing and have a bunch of existing code that we could adapt.
parboiled2 was mentioned in my interview (not by me) – I’d enjoy a chance to actually use it!

Closing until we actually work on Calm data.
