Defines C++ wrapper to log/print text messages.
This API uses C++ variadic templates and type detection to make it easy to print any native type. You can even overload the [print()](#print()) method for your own custom types.
Example:
print( "hello world, this is a number: ", 5 );
Overriding Print for your TypesThere are two ways to overload print:* implement void print( const T& )
- implement T::print()const
