the class RestUtils method trimRecordTemplate.

   * override parameter.

   * An exception will be thrown if this is done.
   *
   * @param dataMap represents the DataMap that will be trimmed.
   * @param schema represents the schema that the datamap should match.
   * @param override represents the MaskTree that defines how fields outside the schema should be preserved.
   * @param failOnMismatch true if an exception should be thrown if there is a data-schema mismatch.
