Caching neighbor indices
------------------------

Defined in ``fastscapelib/grid/base.hpp``.

A very common repetitive task in Fastscapelib is getting the node indices of all
the node neighbors at a given grid node. Using a cache may speed-up this task
(at the cost of memory usage), especially for structured grids with looped
boundaries. In other cases using a cache won't provide any benefit, like for
unstructured meshes where the topology is already fully contained.
