I don't know much about the Loki SmartPtr, but it sounds like it might be a little hard to use if
you need to setup policies...  I wanted to create a very simple AutoPtr that was essentially the
same as the STL auto_ptr (and backwards compatible with it).

Correct me if I'm wrong, but wasn't there a specific reason why the STL auto_ptr was made so it
couldn't be passed to or returned from a function?  I don't have my Stroustrup book with me to
check.
Anyways, if you want to pass or return the pointer to/from a function, just use the .get() or
.release() functions.

I need the m_Owner variable to tell me if I own the pointer before I delete it.
