org.apache.poi.ss.util.CellRangeAddressList
Implementation of the cell range address lists,like is described in OpenOffice.org's Excel Documentation: excelfileformat.pdf sec 2.5.14 - 'Cell Range Address List' In BIFF8 there is a common way to store absolute cell range address lists in several records (not formulas). A cell range address list consists of a field with the number of ranges and the list of the range addresses. Each cell range address (called an ADDR structure) contains 4 16-bit-values.
