Detailed Description

Zick & Homsy grid convergence of the COLLOCATED schemes, in the protocol the
staggered-vs-collocated example page quotes (warm_tol 1e-7, tail 40, up to 4000 steps).

Regenerates the page's collocated columns now that "gauge-exact" (the former set_face_interp(9))
is the default. Reproducing the published "plain" column is the control that the harness matches
the earlier runs.
