\ccDefinition
%============
The default envelope-diagram class used by the envelops functions to represent
the lower or the upper envelope of a set of curves. It is parameterized by a
traits class, which is a model of the \ccc{ArrangementXMonotoneTraits_2}
concept, in case we handle only envelopes of $x$-monotone curves, or of the
refined \ccc{ArrangementTraits_2} concept in case we handle arbitrary planar
curves.
This class is the default envelope-diagram class used by envelope functions
to represent the minimization or the maximization diagram of a set of curves.
It represents the diagram as a doubly-linked list of interleaved vertices
and edges. Thus, all operations provided by the envelope diagram take constant
time, and the space needed to store the diagram class is linear in the
complexity of the envelope.
The space needed by this envelope-diagram class is linear in the size of
the minimization diagram, and traversing requires linear time.
The envelope-diagram class is parameterized by a traits class, which is a
model of the \ccc{ArrangementXMonotoneTraits_2} concept, in case we handle
only envelopes of $x$-monotone curves, or of the refined
\ccc{ArrangementTraits_2} concept in case we handle arbitrary planar curves.
