title: Using Processing, how can I iterate across the files/images in my sketch's data directory?
body: <p>I want to load a bunch of images (or files but there doesn't seem to be an object/type for that) -- not by name, but just whichever ones are in the data directory, into an array or something.  Is there some method for doing that?  The docs make it look impossible and searching the Processing forums doesn't turn anything up.  But it's kind of hard to believe that it's an omission.</p>
  
  <p>Any hints?  Thanks!</p>
