      * This method generated the template parameter list to populate the pdf invoices that are attached to the Document.
      * The evident goal of this method was to return practically any possible property from the given document into a Map which could be stamped on any invoice PDF.  Given that, we've done some strange
      * tricks with Map implementations.  First, we wrap the document in a ReflectionMap, which means that all nested properties from the document can be read via Map notation.  We still have a number of properties
      * we want to add, though, for instance for the payee and the award.  So we wrap ReflectionMap in a FallbackMap, which will treat a regular HashMap and the ReflectionMap as if they were one Map for the sake of
      * getting at least.  Finally, we wrap the map of all properties into a PdfFormattingMap, which formats any values to be returned through get() into properly formatted Strings.
      * @param document the ContractsGrantsInvoiceDocument to convert into a Map form
      * @return a Map.  With everything.
