-// Code for testing the timing: run all possible 1- and 2-bit error 
-// the test message by all 1-bit errors. Run the old code against

-// Example measurements:
-// Timing old vs. new crc correction code:
-//    Old code: 1-bit errors on 112 msgs: 3934 usecs
-//    New code: 1-bit errors on 112 msgs: 104 usecs
-//    Old code: 2-bit errors on 6216 msgs: 407743 usecs
-//    New code: 2-bit errors on 6216 msgs: 5176 usecs
-// indicating a 37-fold resp. 78-fold improvement in speed for 1-bit resp.
-// 2-bit error.
