Remarks
A generator is a class that generates data on demand. In this implementation, generators implement the IGenerator interface, and through an extension method supports a Next method that returns an element every time it is called.
Generators are infinite.
Many methods make methods from existing generators. The existing generators are always cloned, so no derived generator will call the Next<TSource>(IGenerator<TSource>) or MoveNext() methods of an existing generator. Clones are always returned in the restarted state.
Although Generators have almost the same interface as IEnumerator, there are some differences. Generators are always in a "valid" state, so calls to Current will always return a valid result, there is no "before first" and "after last" states.
You can also implement your own generators. There are two ways to do this. The first is to simply use the static methods provided; they allow you to make new generators by manipulating existing ones.
The second way is appropriate for more complicated situations, and that is to define your own class that implements the IGenerator<TResult> interface.
