    Urlgrey is a library for url manipulation. It's got a chainable/fluent interface that makes a number of methods available for querying different aspects of a url, and even modifying it to create new urls.

    Most methods are named after different parts of the url and allow you to read that part from the current url if you don't pass any parameters, or they allow you to generate a new url with a change to that part in the current url if you do pass a parameter.

    For the examples below, we'll use the following url:

    https://user:pass@subdomain.asdf.com/path/kid?asdf=1234#frag
    

    To create a new urlgrey object, just pass a url to urlgrey like so:

    var url = urlgrey("https://user:pass@subdomain.asdf.com/path/kid?asdf=1234#frag")

    API specifics:

    url.child([lastPart])

    Setter/getter for the last part of a path:

      url.child(); // returns "kid" 
      url.child("grandkid"); // returns a new uri object with the uri 
                                 // https://user:pass@subdomain.asdf.com/path/kid/grandkid?asdf=1234#frag

    url.decode(encodedString);

    Returns the decoded version of the input string using node's standard querystring.unescape().

          url.decode('this%20is%20a%20test');  // returns "this is a test"

    url.encode(unencodedString);

    Returns the encoded version of the input string using node's standard querystring.escape().

          url.encode('this is a test'); // returns 'this%20is%20a%20test'

    url.hash([newHash])

    Setter/getter for the url fragment/anchor/hash of a path.

          url.hash(); // returns 'frag'
          url.hash("blah"); // returns a new uri object with the uri
                                // https://user:pass@subdomain.asdf.com/path/kid/?asdf=1234#blah

    url.hostname([newHostname])

    Setter/getter for the url hostname.

          url.hostname(); // returns 'subdomain.asdf.com'
          url.hostname("geocities.com"); // returns a new uri object with the uri
                                // https://user:pass@geocities.com/path/kid/?asdf=1234#frag

    url.parent();

    Get the parent URI of the current URI. (This property is read-only).

          url.parent();  // returns a new uri object with the uri
                         // https://user:pass@subdomain.asdf.com/path/

    url.password([newPassword]);

    Setter/getter for the password portion of the url.

          url.password(); // returns 'pass'
          url.password("newpass"); // returns a new uri object with the uri
                                // https://user:newpass@subdomain.asdf.com/path/kid/?asdf=1234#frag

    url.extendedPath([string]);

    Setter/getter for the path, querystring and fragment portion of the url all at once.

          url.extendedPath(); // returns '/path/kid?asdf=1234#frag'
          url.extendedPath("/newpath?new=query#newfrag"); // returns a new uri object with the uri
                                   // https://user:newpass@subdomain.asdf.com/newpath?new=query#newfrag

    url.path([mixed]);

    Setter/getter for the path portion of the url.

          url.path(); // returns '/path/kid'
          url.path("newpath"); // returns a new uri object with the uri
                                   // https://user:newpass@subdomain.asdf.com/newpath
    
          // ALSO, .path() can take arrays of strings as input as well:
          url.path(['qwer', '/asdf'], 'qwer/1234/', '/1234/'); 
                          // this returns a new uri object with the uri
                          // https://user:newpass@subdomain.asdf.com/qwer/asdf/qwer/1234/1234

    Note: changing the path will remove the querystring and hash, since they rarely make sense on a new path.

    url.port([newPort]);

    Setter/getter for the port portion of the url.

          url.port(); // returns 80
          url.port(8080); // returns a new uri object with the uri
                              // https://user:pass@subdomain.asdf.com:8080/path/kid/?asdf=1234#frag

    url.protocol([newProtocol]);

    Setter/getter for the protocol portion of the url.

          url.protocol(); // returns 'https'
          url.protocol("http"); // returns a new uri object with the uri
                                    // http://user:pass@subdomain.asdf.com/path/kid/?asdf=1234#frag

    url.query([mixed]);

    Setter/getter for the querystring using javascript objects.

          url.query(); // returns {asdf : 1234}
          url.query(false); // returns a new uri object with the querystring-free uri
                                // https://user:pass@subdomain.asdf.com/path/kid#frag
          url.query({spaced : 'space test'})
                                    // returns a new uri object with the input object serialized
                                    // and merged into the querystring like so:
                                    // https://user:pass@subdomain.asdf.com/path/kid/?asdf=1234&spaced=space%20test#frag

    NOTE: escaping and unescaping of applicable characters happens automatically. (eg " " to "%20", and vice versa)

    NOTE: an input object will overwrite an existing querystring where they have the same names.

    NOTE: an input object will remove an existing name-value pair where they have the same names and the value in the input name-value pair is null.

    url.queryString([newQueryString]);

    Setter/getter for the querystring using a plain string representation. This is lower-level than .query(), but allows complete control of the querystring.

          url.queryString(); // returns asdf=1234  (notice there is no leading '?')
          url.queryString("blah"); // returns a new uri object with a new querystring
                                   // https://user:pass@subdomain.asdf.com/path/kid?blah#frag

    NOTE: no escaping/unescaping of applicable characters will occur. This must be done manually.

    url.rawChild();

    This method is the same as url.child() but does not automatically url-encode any part of the input.

    url.rawPath();

    This method is the same as url.path() but does not automatically url-encode any part of the path.

    url.rawQuery();

    This method is the same as url.query() but does not automatically url-encode any of the keys or values in an input object.

    url.toJson();

    Returns the json representation of the uri object, which is simply the uri as a string. The output is exactly the same as .toString(). This method is read-only.

      url.toJson(); // returns "https://user:pass@subdomain.asdf.com/path/kid/?asdf=1234#frag"

    url.toString();

    Returns the string representation of the uri object, which is simply the uri as a string. This method is read-only.

          url.toString(); // returns "https://user:pass@subdomain.asdf.com/path/kid/?asdf=1234#frag"

    url.username([newUsername])

    Setter/getter for the username portion of the url.

          url.username(); // returns 'user'
          url.username("newuser"); // returns a new uri object with the 
                                   // uri https://newuser:pass@subdomain.asdf.com/path/kid/?asdf=1234#frag
