6/// The `NumLike` trait is just a shorthand definition for any "number-like" 
7/// type in Rust. "Number-like" means that a type implements the traits for 
8/// standard arithmatic (Add, Sub, Mul, Div, AddAssign, SubAssign, MulAssign, 
9/// DivAssign, and Neg), plus Clone, Debug, and Display. Most number types also
10/// implement the Copy marker trait, but that is not required (for example, an 
11/// arbitrary-precision number type must dynamically allocate memory and thus 
12/// cannot implement Copy).
13/// 
14/// This trait is not meant to be implemented, just for making generic type 
15/// templates more ergonomic. E.g.
16/// ```rust
17/// use simple_si_units_core::NumLike;
18/// 
19/// fn delta_squared<T>(a: T, b: T) -> T where T: NumLike {
20///   let delta = b - a;
21///   return delta.clone() * delta;
22/// }
23/// ```
