/** Verifies if a purchase is valid by e.g. doing a post-back validation on a server. Place the following two jar-files onto your
 * server (you won't need any other libGDX libraries on your server, all dependencies to libGDX have been removed for easy
 * integration):
 * <ul>
 * <li>gdx-pay.jar
 * <li>gdx-pay-server.jar
 * </ul>
 * <p>
 * How to integrate in your server:
 * 
 * <pre>
 * // create a manager which returns "true" by default  
 * PurchaseVerifierManager verifier = new PurchaseVerifierManager(true);
 * 
 * // add the various purchase verifiers
 * verifier.addVerifier(new PurchaseVerifierAndroidGoogle(...));
 * verifier.addVerifier(new PurchaseVerifierAndroidAmazon(...));
 * verifier.addVerifier(new PurchaseVerifierAndroidOUYA(...));
 * verifier.addVerifier(new PurchaseVerifieriOSApple(...));
 * ...
 * 
 * // verify a purchase
 * if (verifier.isValid(transaction)) {
 *   // transaction appears valid
 *   ... add to DB etc. ...
 * }
 * else {
 *   // transaction appears bogus
 *   ... punish user ...
 * }
 * </pre>
 * 
 * IMPORTANT: this code runs on your SERVER! Don't use on your client-application (not secure).
