Changelog of @hackage/hgeometry 0.7.0.0

Compatibility with GHC 8.0-8.4
Implemented more Algorithms and Data Structures. This includes
- Polygon triangulation
A new implementation of PlanarSubdivision that now also supports disconnected subdivsions.
Performance improvements by changing to a different Vector implementation. For low dimensional vectors (of dimension at most four) we now essentially use the types from linear, this gives significant speedups on several small benchmarks.
bugfixes.

Implemented more Algorithms and Data Structures. This includes
- Bentley-Ottmannn line-segment intersection,
- Well-Separated Pair decompositions,
- extremal point/tangents for Convex hulls,
- Minkowski sum for convex polygons,
- one dimensional segment trees,
- one dimensional interval trees, and a
- KD-tree.
Several bug fixes, including a very stupid bug in Box
Separate ConvexPolygon type.
More thorough testing for some of the algorithms.
Started work on a proper representation for planar subdivsions. This includes a representation of planar graphs that support querying if two vertices are connected by an edge in \(O(1)\) time.
Dropped support for GHC 7.8

Implemented several algorithms, including Delaunay Triangulation, EMST, and Douglas Peucker.
Revamped the data types for Intersections

Major rewrite from scratch, providing much stronger type-level guarantees. Incompatible with older versions.
Convex Hull and Smallest enclosing disk algorithms.
HGeometry now includes some very experimental and preliminary support for reading and writing Ipe7 files.

Fixed a bug in point on n the line segment test
Generalized the types of inCircle, inDisc, onCircle, onDisc etc. We now need only that the type representing precision model implements the typeclass Num instead of `Floating'.
