Originally the only supported geometry specification were triangulated surfaces, hence the name of the directory: constant/triSurface, however now that other surface specifications are supported and provided it is much more logical that the directory is named accordingly: constant/geometry. All tutorial and template cases have been updated. Note that backward compatibility is provided such that if the constant/geometry directory does not exist but constant/triSurface does then the geometry files are read from there.
