Serving IT up with XML.

I hope that your weeks are progressing well. This is the same source that serves up the XHTML, but it now has an XML configuration file which holds the name of the file being served. We will evolve this over the next few weeks so it determines how it should replace the stencil tags from the XML file also. The only new method is readingTheDirectoryXMLFile.

Read and process it carefully. It will be changing some in the coming weeks, but its basic function will be the same. NOTE: I place the directory.xml file in the same folder as the stencil XHTML file. We can adjust the CABOOSE system's file structure later. Continue your good work, Team. La-La.
