Detailed Description

This class provides some simple code to recognize the encodings of XML files. This recognition only does very basic sensing of the encoding in a broad sense. Basically its just enough to let us get started and read the XMLDecl line. The scanner, once it reads the XMLDecl, will tell the reader any actual encoding string it found and the reader can update itself to be more specific at that point.
