/**
* Plugin implementation of the embargo setting function. The parseTerms()
* method performs a look-up to a table that relates a terms expression
* to a fixed number of days. Table constructed from a dspace.cfg property
* with syntax:
*
* embargo.terms.days = 90 days:90,1 year:365,2 years:730
*
* That is, an arbitrary, comma separated, list of <terms>:<days> where <terms>
* can be any string and <days> must be a positive integer.
* All the <terms> fields should be defined in a 'value-pairs' element,
* and the field configured as the embargo terms should employ a drop-down using
* that element in input_forms.xml, if user submission is desired.
