/**
 * Reader In many situations, you want the ability to reset an XMLStreamReader. (Or at least ask if
 * the XMLStreamReader is resettable).
 * 

 * The Reader abstract class: - accepts an XMLStreamReader - provides reset() and isResettable()
 * methods Adds support resettable support to XMLStreamReader
 * 

 * Derived classes must pass the initial reader to the constructor and indicate if it is resettable.
 * Derived classes must also provide an implementation of the newReader() method if resettable.
