/**
 * This file contains the two classes which store details of products returned by AWS.
 *
 * The two classes are {@link LiteDetails}, which stores information obtained by making a 'lite'
 * request; and {@link HeavyDetails}, which is created when making a 'heavy' request.
 *
 * Apparently the lite/heavy request types are going to change in AWS4, so this may
 * change (drastically?) in future releases.

 * As of version 0.3RC1 this is a list of the information returned by AWS that is

 * - <i>Artists</i> of a CD or casset ({@link getArtists()})

 * - <i>Authors</i> of a book ({@link getAuthors()})
 * - Current <i>Availability</i> of a product ({@link getAvailability()})
 * - <i>Catalog</i> of a product ({@link getCatalog()})
 * - URLs of a <i>Product's image</i> ({@link getImage()})
 * - <i>List Price</i> of a product ({@link getListPrice()})
 * - <i>Manufacturer</i> of a product ({@link getManufacturer()})
 * - <i>Amazon's Price</i> for a product ({@link getOurPrice()})
 * - <i>Product's name</i> ({@link getProductName()})
 * - <i>Release Date</i> of a product to the market ({@link getReleaseDate()})
 * - <i>URL</i> of the product's details page on Amazon ({@link getURL()})
 * - Lowest <i>Used Price</i> at Amazon Marketplace. Note, however, that Third Party searches

    *   If an image is not returned, amazOOP tries different store codes to go around this.
