The linear iterators are conformant to STL iterators. For a
description of their interface see OpenMesh::Concepts::IteratorT.
For efficiency reasons the \c operation++(int) (post-increment)
and \c operation--(int) (post-decrement) are not implemented.
Hence, when using iterators, use the pre-increment operation
(++it).
Additionally to the standard operations, each linear iterator
provides a method \c handle(), which returns the handle of the
item referred to by the iterator.
When using iterators, use the pre-increment operation (++it) for efficiency
reasons.
\deprecated
While it is possible to use \c handle() to get the handle of the item referred
to by the iterator, this function is deprecated. Simply dereference the iterator
instead.
