 * Created on December 6th, 2014, 1:25 PM, modified on Dec 7th at 1:33 PM to 
 * add additional documentation. 
 * 
 * This is the header file for various output functions for the DOM tree,
 * such as printing with the serializer, printing with the tree-walker, exporting
 * to an XML file and the 'help' command.
 * 
 * This program is to demonstrate use of regular expressions to parse command line
 * user input along with using the Xerces library to create a DOM structure. 
 * This is an expansion of the previous assignment which was to create a 'hard-coded'
 * DOM structure in memory and to display it to the user. This assignment goes further
 * by building the tree dynamically from the user's requests as well as giving the
 * user various options for tree manipulation. All basic commands are parsed with
 * regular expressions to extract keywords and variable reflecting the meaning of the user's input.
