*
* Recall from the Teuchos RCP documentation that one should never
* create directly a smart pointer from a raw pointer; rather, smart
* pointers should be created through a call to rcp(). The type of the
* argument to rcp() must be known at compile time. This makes the syntax
* \code ConstHandle h = new Derived(); \endcode impossible with the
* straightforward implementation in which ConstHandle takes a raw pointer
* to a Base. In order to preserve this clean syntax, we require any handles
* supporting this syntax to take a raw pointer to a ConstHandleable<Base>,
* where ConstHandleable<Base> provides a getConstRcp() method which returns
* the result of a call to rcp() on this.
