Supports your desktop application in accessing penlet data from a desktop Container. 

This class represents a smartpen item. In the container, it is identified by a path like this: userdata\[Pen Serial]. A smartpen is uniquely identified by a 64-bit unsigned integer. As a number, it is called the "smartpen ID" (or, "pen ID"). As a string, it is called the "smartpen serial," (or, "pen serial"). Smartpen IDs are created by Livescribe when the smartpen is manufactured. 

Each PenItem contains a collection of one or more AppItem objects.
