Multiscale entropy in the source code

[Datseris]

In the current source we have

# TODO: What's this file? It's incomplete and with rogue code...

struct MultiscaleEntropy end

"""
    multiscale_entropy(x::AbstractVector)

"""
function multiscale_entropy end

function coarse_grain(x::AbstractVector{T}, τ) where T
    N = length(x)
    ys = Vector{T}(undef, 0)

    for j = 1:floor(Int, N/τ)
        yⱼ = 0.0
        for i = (j-1)*τ+1:j*τ
            yⱼ += x[i]
        end
        yⱼ *= 1/τ
        push!(ys, yⱼ)
    end
    return ys
end

x = rand(3 * 10^4 )
y1 = coarse_grain(x, 1)
y2 = coarse_grain(x, 2)
y3 = coarse_grain(x, 3)
y4 = coarse_grain(x, 4)
y5 = coarse_grain(x, 5)
y6 = coarse_grain(x, 6)
y7 = coarse_grain(x, 20)

I'm guessing that in the future can be used to estimate some multiscale entropy. But is it really an entropy or a probabilities estimator?

This code is obviously not used for anything, because it is not finished yet. It must have slipped in unnoticed for some PR during this reorganization.

For now, we can just remove this file in #101. I'll have a PR with much nicer interface ready for multiscale entropy/probability once we finish the API reorganization.

This is solved in #132
