What's a quark?

["B. Fallenstein" <b.fallenstein@xxxxxx>]

Hi Tuomas,

In your new merge terminology, how exactly is a quark defined? Consider
cell neg and cell pos, which are connected on dimension dim. Are neg's
posward and pos' negward connection different quarks-- or is the whole
connection, from neg to pos, a single quark? In the Design Problems doc,
it sounds like you mean the former, but in the change list code, it
sounds like the latter.
