 Pathname#dirnames method to iterate on parent directories

* Doc: 

* Gem:

## Introduction

This gem has one method: Pathname#dirnames.

It will return an enumerable of pathnames created by calling #dirname repeatedly.

This can be useful for traversing directories upwards to parent, grandparent, etc.

Example:

     p = Pathname.new('/foo/goo/hoo.txt')

     p.dirnames

     #=> ['/foo/goo', '/foo', '/']

## Install

### Gem

To install this gem in your shell or terminal:

    gem install sixarm_ruby_pathname_dirnames

### Gemfile

To add this gem to your Gemfile:

    gem 'sixarm_ruby_pathname_dirnames'

### Require

To require the gem in your code:

    require 'sixarm_ruby_pathname_dirnames'

## Example to find a file

To find the first occurance of a file named "my.txt" in a path or its parents:

     basename = "my.txt"

     p = Pathname.new('/foo/goo/hoo/*')

     puts p.dirnames.find{|dirname| (dirname + basename).exist?}

Note that the "*" at the end of the pathname is to give dirname something to chop off; the "*" is being used as chaff, not as a file matcher nor string matches.
