added support of list - first effort
fixed code formatting
list support second attempt

modified Introspector so that it does not return a new representation ListClazz when a resource returns a list of Clazz. Fixed it returning a boolean Array = false. Protected field items of resourceOperationDeclaration against NPEs. Fixed class ReflectUtils in Swagger extension.
fixed alphabetical ordering

put alphabetical ordering of RWADef's representations/resources lists in method toDefinition instead of method sendDefinition so that they are sorted in Swagger extension as well as in AS extension.
