* A collection of pointers to OSM objects. The pointers can be easily

* themselves or the buffers they are in, do not have to be changed.
*
* An iterator is provided that can iterate over the pointers but looks
* like it is iterating over the underlying OSM objects.
*
* This class implements the visitor pattern which makes it easy to
* populate the collection from a buffer of OSM objects:
*
* osmium::ObjectPointerCollection objects;
* osmium::memory::Buffer buffer = reader.read();
* osmium::apply(buffer, objects);
*
* It is not possible to remove pointers from the collection except by
* clearing the whole collection.
