Matrix control support pagination method for columns/rows.
eg. every 4 columns * 5 rows per page. At the same time allow adding multiple title/header rows for the matrix. They are more usefull when there are more then 2 dimensions in the matrix. we can promote one of the row filed dimension info to the title/header level to explain some common information for the column fields and repeat the header dimension info on each paginated page.
