This revision includes the following changes:

  [1] app/index.php includes some static examples of content it is intended to display the final product. In conjunction with main.css, this page was built to be styled by this stylesheet. In a later revision, the static content will be removed.
  [2] The Audio_Caching_Manager class now looks for a custom metadata tag in the MP3 file for the recording date. If this is not found, the recording date is considered to be the file's last modified time.
