=head1 NAME

Gitalist::Model::CollectionOfRepos - Model::CollectionOfRepos module for Gitalist

=head1 DESCRIPTION

This Model is a factory for an object implementing the L<Gitalist::Git::CollectionOfRepositories>
interface.

The simple options passed on the command line (like C<--repos_dir>), a class will by picked by default 
L<Gitalist::Git::CollectionOfRepositories::FromDirectory>.

This can be overridden from config by explicitly passing in a class name and args for that class
in config:

    <Model::CollectionOfRepos>
        class MyClassName
        <args>
            ...
        </args>
    </Model::CollectionOfRepos>
