imread is a simple library which reads and saves images from disk to and from numpy arrays. Its goal is to perform this task simply, so that it can become very stable, leaving more complex image processing for other packages.
Grid Engine (C++) is a C++ templated data structure for storing grids of information.
The grids may be connected in a D4 (Manhatten),
or hexagonal sense.
The grids may also wrap toroidally so their edges are connected.
