Replace ResumptionTokenTest by a real junit test

public static void main(String[] args) {
 	 		        String sample = "<resumptionToken cursor=\"100\" completeListSize=\"421653\">oai_dc/421653/56199935/200/0/447/x/x/x</resumptionToken>";
 	 		        String pattern = "(?i)<resumptionToken\\s*cursor=\"[0-9]+\"\\s*completeListSize=\"[0-9]+\">\\s*(.*)</resumptionToken>";
 	 		        Matcher m = Pattern.compile(pattern).matcher(sample);
 	 		        if (m.find()) {
 	 	            System.out.println("PURE pattern found" + m.group(1) );
 	 	            
 	 	  }
 	 	 }
