Feature: Check if directory has given sub directories

  If you need to check if a given directory has given sub dirctories, you can
  use the `have_sub_directory`-matcher.

  ```ruby
  require 'spec_helper'

  RSpec.describe 'Check if directory has sub-directory', :type => :aruba do
    let(:file) { 'file.txt' }
    before(:each) { touch(file) }

    it { expect(file).to be_an_existing_file }
  end
  ```
