Detailed Description

This is a basic, non-optimized implementation of a big integer using strings. In most circumstances this would be considerably slower than other approaches, but given the way in which Trieste nodes store their content as Location objects into a source document, and this class operates over those Locations, it is actual quite efficient when compared to parsing and serializing the Location into a vector of unsigned longs.
