CompileString
A tiny header to manipulate "raw strings" in a std::string fashion at
compile-time.
A toString function on integers is provided in its own header if needs be.
How it works
CompileString is templated over the length of the string (CompileString<4>)
and holds a std::array<char, N + 1> (N being the length of the string, + 1 to store the end-of-string character \0).
In order to add two strings, you need to add their lengths and allocate a new
array. This means that the type returned by operator+ is different from the
type of its 2 operands. A CompileString is only assignable to another if both
their lengths are the same.
