v0.2.0

This release marks a major overhaul to the library's interface.

Changed

• BREAKING CHANGE: Simplified return type of dijkstra and aStar.
  • This should make these functions more ergonomic.
  • Introduced new incrementalCosts function to compensate.
• BREAKING CHANGE: Replaced searches' prunes arguments with pruning combinator.
• BREAKING CHANGE: Split searches' next arguments into multiple arguments for dijkstra and aStar.
  • This should make these functions more ergonomic.
• next arguments now only require a way of generating Foldables, instead of lists specifically.
