Full Changelog: 0.1.3...0.2.0

0.1.3

What's Changed

New Features

honeycomb-core

^{core definitions and tools for combinatorial map implementation}

• Orbit<'a, const N_MARKS: usize, T: CoordsFloat> - Generic implementation for
  2D orbit computations. The structure itself only contains meta-data, the orbit
  computation is done through the Iterator trait implementation (#18)
• OrbitPolicy<'a> - Enum used to specify the beta functions used by an orbit.
  It currently does not support compositions (#18)
• New (temporary?) method for TwoMap: beta_runtime. It works by redirecting
  to the original beta method, using match block and a beta identifier provided
  at runtime (#18)

honeycomb-guide

^{mdbook-based user guide with information regarding usage & non-code-related
aspects of the project}

• update content of the workspace section to include new member (#19)
• update honeycomb-core's page content (#19)

honeycomb-render (new member)

^{visualization tool for combinatorial maps}

• implement TwoMap rendering code
• add examples illustrating basic usage
