 qr.py
-  some stuff
+  Quadratic Residue FEC for use in generating EMB data. In reality, the EMB can be generated from a lookup table more effectively than calcuating the QR FEC and creating the EMB from scratch because in amateur radio use (as of today) only a limited number of EMBs will actually ever be used. Routines here have not been completed for this reason, but may be some day.
