 * _ttl_ <int> Optional. Number of minutes feed can be cached before refreshing from source.

### Item Options

In RSS an item can be used for a blog entry, project update, log entry, etc.  Your rss feed
an have any number of items. Ten to tenty is usually good.

 * _title_ <string> Title of this particular item.
 * _description_ <string> Content for the item.  Can contain html but link and image urls must include the server name.
 (Note: I might change this to content in the next release.)
 * _url_ <url> Url to the item. This could be a blog entry.
 * _guid_ <unique string> A unique string feed readers use to know if an item is new or has already been seen.
 If you use a guid never change it.  If you don't provide a guid then your item urls must
 be unique.
 * _categories_ <array> Optional. If provided, each array item will be added as a category element
 * _author_ <string> Optional.  If included it is the name of the item's creator.
 If not provided the item author will be the same as the feed author.  This is typical
 except on multi-author blogs.
 * _date_ <Date object or date string> The date and time of when the item was created.  Feed
 readers use this to determine the sort order. Some readers will also use it to determine
 if the content should be presented as unread.

### Methods

 * _item(item_options)_ - add an rss item, article, entry etc.
 * _xml([indent])_ - return the xml.  If you pass in true it will use four spaces for indenting. If you prefer
 tabs use \t instead of true.

## Tests

 Mocha tests are included. Use `npm test` to run the tests.

    $ npm test

## Notes
 * You do not need to escape anything. This module will escape characters when necessary.
 * This module is very fast but you might as well cache the output of xml() and serve
 it until something changes.
