the class HierarchicalTreeLayer method expandOrCollapse.

 * given, only the first level of a row is expanded, given toLevel is 1 and
 * a node in the first level should be expanded, that node will be expanded
 * as well as all collapsed nodes in the second level for this object.
 *
 * @param columnIndex
 *            The column index of the node to handle.
 * @param rowIndex
 *            The row index of the node to handle.
 * @param toLevel
 *            0 based hierarchy level to expand to. Will be ignored on
 *            collapse or if value is -1.
 *            <p>
 *            <b>Note:</b> This is the level to expand to, not the number of
