Puts a zero (0) in the monthly absence track pages of MASSAR sgs.. It can also empty all entries with the zero value (0).
This extension simplifies the monthly absence track in MASSAR sgs webpages... It appends two buttons in concerned webpages: - The 1st button nullifies (puts 0) the empty entries. - The 2nd button cancels the nullification by emptying entries that contain "0".
