[ANN] Fatou.jl : Easily share Julia fractals

[chakravala]

This is an announcement update, Fatou version 1.0.1 has been released, which now has a significant performance improvement due to the suggestion by @ckoe-bccms with parametric types

Structs and parametric constructors

When I only add the Function parameters to the Define type, I get basically 0% to 10% improvement. My original timings look like this julia> newton(:(z^3-1);n=500)|>fatou; 0.240635 seconds (1.69 M allocations: 58.407 MiB) With the Define{FT<:Function,QT<:Function,CT<:Function} definition, I don’t get much improvement julia> newton(:(z^3-1);n=500)|>fatou; 0.221504 seconds (1.53 M allocations: 50.724 MiB) However, because in my situation there is additional program logic, I added additio…

This should fix the issue with the high memory allocation for large n, allowing bigger fractals, faster

julia> newton(:(z^3-1);n=3500)|>fatou;

The testing behavior of the package is a bit weird on some platforms, but with PyPlot, it should work.
