# Certain fields we add to the Item/Copy/Bib display are in the XML, but they
# are only findable by name of the field header as configured in HIP
# admin, and then only by seeing what index in a list that header is,
# and then finding the corresponding indexed value! This object
# does that work for us, and caches it's calcuations while it's at it.
# One of these objects has it's own rexml doc representing a particular
# bib with item info, because the answer may be different for different bibs!
