+\file
+\brief Basic tests of the nonfinite num facets.
+
+\detail Basic_test outputs using nonfinite_num_put facet
+and reads back in using nonfinite_num_ facet,
+and checks loopback OK.
+
+Also checks that output of infinity, -infinity and NaN are as expected,
+using C99 specification  "nan -nan nan -nan" and "inf -inf".
+Also includes a few combinations of display manipulators
+(left, right, internal, showpos)
+and checks that can input C99 infinity and NaN too.
