added methods for checking initWithData Just copied from SimpleDataErrorTests and replaced stringWithContentsOfFile with dataWithContentsOfFile and init with data accordingly Added methods jsonmodel#1. testErrorsInNestedModelsDictionary jsonmodel#2. testErrorsInNestedModelsArray jsonmodel#3. testMissingKeysError jsonmodel#4. testTypeMismatchErrorImages jsonmodel#5. testTypeMismatchErrorImagesObject
