/**
* @class journal_builder_t
*
* @brief This custom builder creates an XML-mirrored Ledger journal.
*
* Rather than simply creating a node_t hierarchy, as xml_builder_t
* does, this code creates the associated journal elements referred to
* by those nodes, and then refers to those elements via minimalist
* "shadow nodes".
*
* Thus, after building a <transaction> element, the element itself
* will have no children, but instead will point to a transaction_t
* object. If later an XPath expression desires to traverse the
* <transaction> element, all of the appropriate child nodes will be
* constructed on the fly, as if they'd been created in the first
* place by a regular xml_builder_t.
