%  Setup:
%  - 5x5 -> 5x5, extent 1.25x1.25 ->
%  - nodes "freely placed" at regular grid locations
%  - rectangular mask ll: [0.,0.] ur: [0.6,0.3]
%  - anchor [0,0]
%  - should give identical results to reg_mask_rect_00.sli
%
%   nodes in the bottom row connect only to nodes on the corresponding row
%   nodes at the right edge have no connections beyond the edge
