//
// 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
//
// The expression decomposing templates are taken from lest - https://github.com/martinmoene/lest
