Could you provide sample code for Predict?

[zsong]

I want to do text classification. Could you please provide a sample code for the implementation of IDataIter?

Here is want I want to accomplish:

var loadedModel = FeedForward.Load(...);
var result = loadedModel.Predict("Text 1"); //?

So how should I wrap the string "Text 1" as IDataIter? Thank you!
