What is it?

This library provides a single type that can be used to represent any physical SI unit. It provides automatic type safety by ensuring values of differing types can not be operaterated on in illegal ways. For instance, distance + velocity would generate an compile-time error; where as distance + velocity * time is a legal expression.

Example

auto position = Meter<float>(15);
auto velocity = Velocity<float>(10);
auto time     = Second<float>(2);

auto fubar  = position + velocity; //<-- Compilation error
auto result = position + velocity * time;

std::cout << float(result); // "45"
