Uniform civil numbers validation and generation tool

With this android application you can generate, validate and parse (get information for) Bulgarian Unique citizenship numbers. This is my "practice on your own" stage on this android development course, so it works properly, but I am not pretending it to be ideal. :) Here you can watch a short demonstration video. UniformCivilNumber class contains an algorithm from https://georgi.unixsol.org/programs/egn.php which I ported from PHP to Kotlin. The author of the algorithm is Georgi Chorbadzhiyski.
