/**
 * Main entry point to talk to a RunDeck instance.<br>
 * You have 2 methods for authentication : login-based or token-based. If you want to use the first, you need to provide
 * both a "login" and a "password". Otherwise, just provide a "token" (also called "auth-token"). See the RunDeck
 * documentation for generating such a token.<br>
 * <br>
 * Usage : <br>
 * <code>
 * <pre>
 * // using login-based authentication :
 * RundeckClient rundeck = new RundeckClient("http://localhost:4440", "admin", "admin");
 * // or for a token-based authentication :
 * RundeckClient rundeck = new RundeckClient("http://localhost:4440", "PDDNKo5VE29kpk4prOUDr2rsKdRkEvsD");
 * 
 * List&lt;RundeckProject&gt; projects = rundeck.getProjects();
 * 
 * RundeckJob job = rundeck.findJob("my-project", "main-group/sub-group", "job-name");
 * RundeckExecution execution = rundeck.triggerJob(job.getId(),
 *                                                 new OptionsBuilder().addOption("version", "1.2.0").toProperties());
 * 
 * List&lt;RundeckExecution&gt; runningExecutions = rundeck.getRunningExecutions("my-project");
 * 
 * rundeck.exportJobsToFile("/tmp/jobs.xml", FileType.XML, "my-project");
 * rundeck.importJobs("/tmp/jobs.xml", FileType.XML);
 * </pre>
