r"""
The category of polygons in the hyperbolic plane.

EXAMPLES::

    sage: from flatsurf import HyperbolicPlane
    sage: H = HyperbolicPlane()

    sage: P = H.polygon([
    ....:   H.vertical(1).left_half_space(),
    ....:   H.vertical(-1).right_half_space(),
    ....:   H.half_circle(0, 2).left_half_space(),
    ....:   H.half_circle(0, 4).right_half_space(),
    ....: ])

    sage: P.category()
    Category of facade convex simple hyperbolic polygons over Rational Field

    sage: from flatsurf.geometry.categories import HyperbolicPolygons
    sage: P in HyperbolicPolygons(QQ)
    True
