+// Class:  ResultDatabase
+//
+// Purpose:
+//   Track numerical results as they are generated.
+//   Print statistics of raw results.

+// Programmer:  Jeremy Meredith
+// Creation:    June 12, 2009

+// Modifications:
+//    Jeremy Meredith, Wed Nov 10 14:20:47 EST 2010
+//    Split timing reports into detailed and summary.  E.g. for serial code,
+//    we might report all trial values, but skip them in parallel.
+//
+//    Jeremy Meredith, Thu Nov 11 11:40:18 EST 2010
+//    Added check for missing value tag.
+//
+//    Jeremy Meredith, Mon Nov 22 13:37:10 EST 2010
+//    Added percentile statistic.
+//
+//    Jeremy Meredith, Fri Dec  3 16:30:31 EST 2010
+//    Added a method to extract a subset of results based on test name.  Also,
+//    the Result class is now public, so that clients can use them directly.
+//    Added a GetResults method as well, and made several functions const.
