[section Exception safety]

In order to be exception-safe the __rtree__ requires:

* exception-safe copy constructor and copy assignment of the `__value__`.
* exception-safe copy constructor and copy assignment of the `CoordinateType` used in the `Indexable`.
* nonthrowing copy constructor of the `Translator`.
* nonthrowing destructors of above types.
