• Trebuchet diagram showing what the quantities used are refering to

02_02

• Add setindex! method taking a Symbol as index

02_03

• Define -(::Trebuchet, ::Vector) -> Trebuchet
• Constrain aim to result in meaningful angle:

function aim(trebuchet, environment; ϵ = 0.1, η = 0.05)
    better_trebuchet = copy(trebuchet)
    hit = x -> (shoot_distance([environment.wind, x[2], x[1]]) - environment.target_distance)
    while abs(hit(better_trebuchet)) > ϵ
        grad = gradient(hit, better_trebuchet)
        better_trebuchet -= η * grad
        better_trebuchet[2] = better_trebuchet[2] % 2pi
        if better_trebuchet[2] < 0
            better_trebuchet[2] += 2pi
        end
    end; return Trebuchet(better_trebuchet...)
end

• Could write all-in-one function to use Blink with Trebuchet.visualize show the result after calling with starting parameters

• Show process of adding documentation (including with PkgTemplates / Documenter)
