First public release of voc4cat on github.

Earlier releases

Before 0.4.0 the code was in alpha state and kept private.
See git commit log and the issues & milestones in this repository for the early history.

Just before 0.4.0 the code was migrated from a private gitlab instance to github.
The transfer went OK but not perfect (gitlab-MRs were not well converted to github-PRs).
