This class is just for book keeping in the Verbatim class. It stores information about the location of callouts.

Only line/column based callouts are supported. This class implements the Comparable interface so that callouts can be sorted. Callouts are sorted so that they occur in left-to-right, top-to-bottom order based on line/column.
