glazier-core
The lattice, the energies and the serial sweep behind
glazier.
Contact, volume, surface and length energies on a periodic lattice in two or three dimensions, diffusing species with secretion and uptake, chemotaxis, persistent motility, division, death, and a local connectivity test. The Blueprint reader is here too: the JSON description every engine in the workspace agrees on.
The serial sweep is the correctness reference, and every other engine has to agree with it.
