+    regex... but MultiRegex itself gives us no real way to do that.
+
+    So what this class creates MultiRegexs on the fly for whatever search
+    position they are needed.
+
+    NOTE: These additional MultiRegex objects are created dynamically.  For most

+
+    This class wraps all that complexity up in a simple API... `startAt` decides
+    where in the array of expressions to start doing the matching. It
+    auto-increments, so if a match is found at position 2, then startAt will be
+    set to 3.  If the end is reached startAt will return to 0.
