Detailed Description

We have iterators that dereference to dynamics, but need iterators that dereference to typename T.

Implementation details:

1. We cache the value of the dereference operator. This is necessary because boost::iterator_adaptor requires *it to return a reference.
2. For const reasons, we cannot call operator= to refresh the cache: we must call the destructor then placement new.
