Purpose: Build mixed doubles randomly paired rosters for as many as four courts from lists of registered players. Players who registered last and are left unpaired are assigned to wait-lists.

running using iex

Clone the repo and in the project directory:

λ mix deps.get
λ iex -S mix mixed_doubles
λ iex --werl -S mix mixed_doubles (on windows to get tab-completion in the erlang terminal)
