The 'url_builder' parameter is a function that accepts the username, repo and branch/commit, and creates a HTTP/S URL of a Git server. Compatible functions are '__create_github_url', '__create_bitbucket_url'.

The 'username' parameter defines the Github username which is the repository's owner.

The 'repo' parameter defines the name of the repo that contains the modules/packages to be imported.

The 'module' parameter is optional and is a list containing the modules/packages that are available in the chosen Github repository.
