-/**
-*
-* Parses for bulleted and numbered lists.
-*
-* This class implements a Text_Wiki_Parse to find source text marked as
-* a bulleted or numbered list.  In short, if a line starts with '* ' then
-* it is a bullet list item; if a line starts with '# ' then it is a
-* number list item.  Spaces in front of the * or # indicate an indented
-* sub-list.  The list items must be on sequential lines, and may be
-* separated by blank lines to improve readability.  Using a non-* non-#
-* non-whitespace character at the beginning of a line ends the list.
