title: LocalDate interval in Joda-time
body: <p>Joda-time has an <a href="http://www.jarvana.com/jarvana/view/joda-time/joda-time/1.5.1/joda-time-1.5.1-javadoc.jar!/org/joda/time/Interval.html" rel="noreferrer">Interval</a> class, which is a range between <a href="http://www.jarvana.com/jarvana/view/joda-time/joda-time/1.5.1/joda-time-1.5.1-javadoc.jar!/org/joda/time/DateTime.html" rel="noreferrer">DateTime</a>s. What can be used for a range of <a href="http://www.jarvana.com/jarvana/view/joda-time/joda-time/1.5.1/joda-time-1.5.1-javadoc.jar!/org/joda/time/LocalDate.html" rel="noreferrer">LocalDate</a>s?</p>
  
  <p>I want an object that represents, for example "from 1/1/2011 to 10/1/2011", without the time (or timezones) ever coming into the picture.</p>
  
  <p>As far as I see, joda-time doesn't have anything built in for that.
  If there doesn't exist anything for it, and we'd create it, what should it look like? Most importantly, which interfaces from joda-time could it implement to best integrate into the other types, staying consistent with the joda-time design?
  Would it make sense for it to implement <code>ReadableInterval</code>, where <code>getStart</code> and <code>getEnd</code> return <code>DateMidnight</code>?</p>
