Hi,

Can I add discrete non-integer variable constraints such that my design variables are chosen from specified lists of available discrete values in Evolutionary.jl?

I want something similar as in this MATLAB example: **[Add Discrete Non-Integer Variable Constraints](https://www.mathworks.com/help/gads/solving-a-mixed-integer-engineering-design-problem-using-the-genetic-algorithm.html)**.
