## Definition

Refines
  `AdaptableBinaryFunction`

A model of this concept must provide:
bool | operator() (ArrTraits::Point_2 p1, ArrTraits::Point_2 p2)
| determines whether `p1` and `p2` are geometrically equivalent.
bool | operator() (ArrTraits::X_monotone_curve_2 xc1, ArrTraits::X_monotone_curve_2 xc2)
| determines whether `xc1` and `xc2` are geometrically equivalent (have the same graph).
