+ * It stores either Object (defined by Generic {@literal <T>}) or String.<p>

+ *
+ * the "options" available on several functions control the output of this particular call.  When 
+ * blank, they will default to the DataFactory defaults.  When present, they override this
+ * particular call.
+ * 	The available options are "pretty" (for XML and JSON) and "fragment" (XML only concept), which drops
+ * the "<?xml ...?>" header so you can create larger XML documents from the output.
