\ccDefinition
  
The class \ccRefName\ is a model for the \ccc{HalfedgeDS} concept.
\ccRefName\ is a vector-based representation with random
access iterators that does not support removal.

\ccImplementation

\ccRefName\ uses internally the \stl\ \ccc{std::vector} container
class. We require that we can create a \ccc{std::vector::iterator}
from a pointer. If this will not be true any longer for any major \stl\
distribution we might switch to an internal implementation of a vector.

The capacity is restricted to the reserved size. Allocations
are not possible beyond the capacity without calling reserve again.
All handles and iterators are invalidated upon a reserve call that
increases the capacity.

\ccc{CGAL_ALLOCATOR(int)} is used as default argument for the
\ccc{Alloc} template parameter.
