Struct Score

#[repr(transparent)]
pub struct Score {
    pub values: Arc<[f32]>,
}

A score is a value that can be used to compare the fitness of two individuals and represents the ‘fitness’ of an individual within the genetic algorithm. The score can be a single value or multiple values, depending on the problem being solved. For ease of use the Score struct provides methods to convert the score to a single value, an integer, a string, or a vector of f32 values.

Note: The reason it is a Vec is for multi-objective optimization problems. This allows for multiple fitness values to be returned from the fitness function.
