6.16. class UniBlock: One Unicode code block

Each instance of this class represents one of the chunks of code point space handed out by the Unicode Consortium. A block's length is always a multiple of 16.

Because the source of all this data is a node in the unicode.xml file, all the constructor needs is that node as an et.Element.
