Point in circle checks.
Point in ellipse checks.
Inertia tensors for 2D shapes that implement moments of inertia.
Add minimal bounding sphere for all shapes.
Add minimal centered bounding sphere calculations for all shapes except general polygons, general polyhedra, spheropolygons, and spheropolyhedra.
Enable getting and setting the circumsphere or bounding sphere radius of a polyhedron (for both types of bounding sphere).
Add maximal bounded sphere for all shapes.
Add maximal centered bounded sphere calculations for all shapes except general polygons, general polyhedra, spheropolygons, and spheropolyhedra.
Enable getting and setting the insphere or bounded sphere radius of a polyhedron (for both types of bounding sphere).

Point in polyhedron checks for general (nonconvex) polyhedrons.
Minimal bounding sphere for all shapes except spheropolygons and spheropolyhedra.
Add minimal centered bounding sphere calculations for all shapes except general polygons, general polyhedra, spheropolygons, and spheropolyhedra.
Getters and setters for the circumsphere or bounding sphere radius of a polyhedron (for both types of bounding sphere).
A repr for all shapes.

The circumsphere from center calculations (replaced by minimal centered bounding sphere).
The bounding_sphere property is deprecated in favor of minimal_bounding_sphere.
The insphere from center calculations (replaced by maximal centered bounded sphere).

Centroid calculations for polygon and polyhedron use the full integrals rather than simple averages of vertices.

Shape family API is now entirely based on class methods rather than a call operator.
The parent ShapeFamily class is now part of the public API.
Doctests are now run as part of pytest.
Subpackages have been renamed: shape_classes is now shapes, and shape_families is now families.
The common_families submodule of shape_families is now just common.

Volume calculation for ConvexSpheropolyhedron includes area of extruded faces in addition to vertices and edges.
Documentation has been revised and edited.

The symmetry.py module.
The ft.py module.
The symmetry.py module.
The get_params method of TabulatedShapeFamily.
The family_from_doi method (the underlying data dictionary is now directly exposed).

Inertia tensors for polyhedra and moments of inertia for polygons are calculated in global coordinates rather than the body frame.
Modified testing of convex hulls to generate points on ellipsoids to avoid degenerate simplices.
All insphere, circumsphere, and bounding sphere calculations now return the appropriate classes instead of tuples.

Continuous integrated testing on CircleCI.
New Polygon class with property-based API.
New ConvexSpheropolygon class with property-based API.
New Polyhedron class with property-based API and robust facet sorting and merging.

Ability to plot Polyhedra and Polygons.
Can now check whether points lie inside a ConvexPolyhedron or ConvexSpheropolyhedron.
Added documentation.
New Ellipsoid class with property-based API.
New Sphere class with property-based API.
New Ellipse class with property-based API.
New Circle class with property-based API.
Added insphere from center calculation for convex polyhedra.
New ConvexPolygon class.
Documentation is hosted on ReadTheDocs.

Moved core shape classes from euclid.FreudShape into top-level package namespace.
Moved common shape definitions into common_shapes subpackage.
Shapes from Damasceno science 2012 paper are now stored in a JSON file that is loaded in the damasceno module.

Various unused or redundant functions in the utils module.
The quaternion_tools module (uses rowan for quaternion math instead).
The shapelib module.
Old polygon.py and polyhedron.py modules, which contained old implementations of various poly* and spheropoly* classes.
