Add an origin function

[justinmchase]

The origin consists of only the scheme and authority. This change adds the following ways to work with the origin:

URI.buildOrigin(parts);
u.origin()
u.origin(uri)

I think I would have used the existing accessory here as well:

var origin = URI(v);
this
  .protocol(origin.protocol())
  .authority(origin.authority())
  .build(!build);
return this;

While simpler to read, it is slower because of double parsing…

[justinmchase]

so that's better, even with double parsing?

[justinmchase]

I changed it to do this despite double building. Easier to read.

[rodneyrehm]

In test/urls.js a bunch of URLs are listed and expressed in their components to verify various input. Like the resource is a compound of path, query and fragment, the origin should be added to every entry to validate the compound of protocol and authority.

[justinmchase]

I updated the urls.js tests, I found one issue where the protocol is set but the authority is not. In that case the origin is also empty.

e.g.

assert.equal('', URI('http:///foo/bar.html').origin())

looking good, thx! all that's missing now is adding the new method to the docs and having fun with some ascii art. Do you want to try that as well?

[justinmchase]

I added some stuff to docs.html. I'll look at the other one now.

Fixed doco verbage based on your last comment.

[rodneyrehm]

thank you very much :)

[justinmchase]

Thank you! We look forward to getting it in an update.

[rodneyrehm]

I'll try to make that happen tomorrow…
