If you make changes to this file, PLEASE CONSIDER making parallel changes to l_int_matrix.h, whose structure closely parallels the structure of this file. Tip: use vimdiff on both files to show the parallel structure.
Although this class has much the same interface as class Int_matrix, they are not derived from a common abstract interface, because (1) we want as much speed as possible – this code should be eligible to put inside a tight inner loop; and (2) I don't know whether that would be useful.
