// This is a base class for QPDF Object Helper classes. Object helpers
// are classes that provide a convenient, higher-level API for working
// with specific types of QPDF objects. Object helpers are always
// initialized with a QPDFObjectHandle, and the underlying object
// handle can always be retrieved. The intention is that you may
// freely intermix use of document helpers with the underlying QPDF
// objects unless there is a specific comment in a specific helper
// method that says otherwise. The pattern of using helper objects was
// introduced to allow creation of higher level helper functions
// without polluting the public interface of QPDFObjectHandle.
