+//
+// The concept of subcases (sections in Catch) and expression decomposition are from there.
+// Some parts of the code are taken directly:
+// - stringification - the detection of "ostream& operator<<(ostream&, const T&)" and StringMaker<>
+// - the Approx() helper class for floating point comparison
+// - colors in the console
+// - breaking into a debugger
+// - signal / SEH handling
+// - timer
+// - XmlWriter class - thanks to Phil Nash for allowing the direct reuse (AKA copy/paste)
+//
+// The expression decomposing templates are taken from lest - https://github.com/martinmoene/lest
