title: Ignore Field in json in assert operation
body: <p>I'm trying to write a MUNIT test case for mule service and want to ignore a field having timestamp. Currently, i'm using below code to perform the compare.</p>
  
  <pre><code>org.skyscreamer.jsonassert.JSONAssert.assertEquals(getResource('json/item-locations.json').asString(), payload, false);
  </code></pre>
  
  <p>I want to ignore field "creationDateTime" which is available in my json message.</p>
