21* Parses for text marked as a code example block.
22*
23* This class implements a Text_Wiki_Parse to find sections marked as code
24* examples.  Blocks are marked as the string <code> on a line by itself,
25* followed by the inline code example, and terminated with the string
26* </code> on a line by itself.  The code example is run through the
27* native PHP highlight_string() function to colorize it, then surrounded
28* with <pre>...</pre> tags when rendered as XHTML.
