Detailed Description

A smart pointer class that holds a single Sample object.

To avoid various memory management issues, samples are usually held via such a smart pointer. Since the reference count is internal to the Sample object it is safe to assign the same Sample to multiple smart pointers.

Rationale

This class is mostly to make SampleHandler independent of boost, otherwise I could have used boost::intrusive_ptr.
