+- Getting the parallel version to work was a pain. Two major gotchas:
+        (1) -ltbb had to be added *at the end* of the command line
+        (2) clang requires a libstdc++ option to make this work
+  of course everything was terrible to decipher with C++ compile errors
+  being the mess they are.
+- For measuring time I could also use
+        clock_t begin = clock();
+        ...
+        clock_t end = clock();
+        double time = (dobule)(end - begin) / CLOCKS_PER_SEC;
+  but it does not work with the parallel version (it meausres CPU clocks).
