%description
Shortest paths between points in grids. Optional barriers and custom
transition functions. Applications regarding planet Earth, as well as
generally spheres and planes. Optimized for computational performance,
customizability, and user friendliness. Graph-theoretical implementation
tailored to gridded data. Currently focused on Dijkstra's (1959)
<doi:10.1007/BF01386390> algorithm. Future updates broaden the scope to
other least cost path algorithms and to centrality measures.
