Detailed Description

template<class DVL>
class DataModel_detail::const_iterator< DVL >

Const iterator class for DataVector/DataList.

We need to cast dereferences to the appropriate type. This could be done with a boost::transform_iterator, except that the iterator category for that will be one of boost's new-style iterator categories, which don't interoperate well with the standard C++ categories. In particular, the container concept checks didn't work.

This is templated on the specific DataVector/List class.

This used to be done using boost::iterator_adaptor, but that caused problems with root6. So now use just write out the iterator explicitly.
