Overview

Get the imprint information from originInfo elements (and sub elements) to create display strings

This code is adapted from the mods_display gem. In a perfect world, this code would make use of the date_parsing class instead of reimplementing pieces of it; however, the date_parsing class only does years, and this does finer tuned dates and also reformats them according to the encoding.
