Date parsing and utilities for hledger.
For date and time values, we use the standard Day and UTCTime types.
A 'SmartDate' is a date which may be partially-specified or relative.
Eg 2008/12/31, but also 2008/12, 12/31, tomorrow, last week, next year.
Eg 2008\/12\/31, but also 2008\/12, 12\/31, tomorrow, last week, next year.
We represent these as a triple of strings like (\"2008\",\"12\",\"\"),
(\"\",\"\",\"tomorrow\"), (\"\",\"last\",\"week\").
