Canonical name

[craibuc]

Issue

On the gem's home page, you write:

url = Domainatrix.parse("http://www.pauldix.net")
url.canonical # => "net.pauldix"

However, in IRB, I get the following behavior:

irb> url = Domainatrix.parse('http://www.pauldix.net')
=> #<Domainatrix::Url:0x007fd0409d5310 @scheme="http", @host="www.pauldix.net", @url="http://www.pauldix.net", @public_suffix="net", @domain="pauldix", @subdomain="www", @path="">
> url.canonical
=> "net.pauldix.www"

Is the www supposed to be a part of the canonical name?
