Crate game_stat

game_stat gives you the power to modify some base value through modifiers. Most commonly seen in video games

let mut armor_stat: Stat<2> = Stat::new(10f32);
{
    let _modifier_handle = armor_stat.add_modifier(StatModifier::Flat(5f32));
    println!("armor_stat is: {} it should be 15!", armor_stat.value());
}
println!("armor_stat is: {}, It should be 10!", armor_stat.value());

• Stat<2> is a stat that can hold a maximum of 2 modifiers. (the modifiers is an array internally, carefully select a sensible value)
• armor_stat.value() returns our stat value based on what modifiers are active.
• We add a StatModifier, it is valid as long as the StatModifierHandle that is returned from Stat::add_modifier() exists, which is why our value goes back to 10 when it gets dropped from the stack
