Feature: Check if path exists

  If you need to check if a given path exists, you can use the
  `be_an_existing_path`-matcher. It doesn't care if the path is a directory or
  a path.

  ```ruby
  require 'spec_helper'

  RSpec.describe 'Check if path exists', :type => :aruba do
    let(:path) { 'file.txt' }
    before(:each) { touch(path) }

    it { expect(path).to be_an_existing_path }
  end
  ```
