// This is a TTask that makes SDigits out of Hits

+// the created SDigits
+// The title of the TTAsk is the name of the file that contains the hits from
+// which the SDigits are created
// A Summable Digits is the sum of all hits originating
// from one primary in one active cell
// A threshold for assignment of the primary to SDigit is applied
