// The library is heavily influenced by Catch - https://github.com/philsquared/Catch
// which uses the Boost Software License - Version 1.0
// see here - https://github.com/philsquared/Catch/blob/master/LICENSE.txt
//
// 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
// which uses the Boost Software License - Version 1.0
// see here - https://github.com/martinmoene/lest/blob/master/LICENSE.txt

// A 24 byte string class (can be as small as 17 for x64 and 13 for x86) that can hold strings with length
// of up to 23 chars on the stack before going on the heap - the last byte of the buffer is used for:
// - "is small" bit - the highest bit - if "0" then it is small - otherwise its "1" (128)
// - if small - capacity left before going on the heap - using the lowest 5 bits
// - if small - 2 bits are left unused - the second and third highest ones
// - if small - acts as a null terminator if strlen() is 23 (24 including the null terminator)
//              and the "is small" bit remains "0" ("as well as the capacity left") so its OK
