/// **You can only compare objects that share the same currency.** The function also normalizes objects to the same scale (the highest) before comparing them.
///
/// The `Dinero` struct implements `Ord` trait. You can directly comparison operators:

/// ```rust
/// use dinero::{currencies::EUR, Dinero};
///
/// let result = Dinero::new(20, EUR, None) <= Dinero::new(10, EUR, None);
/// ```
