Detailed Description
An implementation of T:IFieldExtractor that returns the original item. If it is an array it is returned as is. Collections, dictionaries, and field sets are converted to array. In any other cases the object is wrapped in a single element array.
This implementation relies on the contravariance of the type parameter of T:IFieldExtractor, thus it can be used at any place where an T:IFieldExtractor is expected as long as the type parameter is a reference type (i.e., if T is the type parameter you should have the following constraint : "<c>where T : class</c>").
