+ * Parses for heading text.
+ *
+ * This class implements a Text_Wiki_Parse to find source text marked to
+ * be a heading element, as defined by text on a line by itself prefixed
+ * with a number of equasl signs (=), determining the heading level.
+ * Equal signs at the end of the line are silently removed.
+ * The heading text itself is left in the source, but is prefixed and
+ * suffixed with delimited tokens marking the start and end of the heading.
