Pathname#dirnames method to iterate on parent directories

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', '/']

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.
