.neigh files
- First line: <# of triangles>
<# of neighbors per triangle (always 3)>
- Following lines: <triangle #>
<neighbor> <neighbor> <neighbor>
Blank lines and comments prefixed by `#' may be placed anywhere.
Triangles are numbered consecutively, starting from one or zero.
Neighbors are indices into the corresponding
.ele file. An index of -1
indicates no neighbor (because the triangle is on an exterior boundary).
The first neighbor of triangle i is opposite the first corner of
triangle i, and so on.
Triangle can produce .neigh files (use the -n switch), but cannot read them.
