Reimplement the 2d implementation of edge orientation.

The old implementation, written in 2003 by Mike Anderson, is quite concise
and of high quality. But it is not extensively documented, and is
unnecessarily hard to read because it uses different conventions for names
etc than we use in the rest of the library.

This reimplementation uses standard conventions, and it uses the language and
symbols of a paper about to be submitted that concisely describes the algorithms
and data structures used in this algorithm. As an additional benefit,
it uses the standard vertex ordering of cells rather than the
old-style ordering used in the existing algorithm.

Following the algorithm without understanding the graph theoretical context
of the problem may be difficult, but because it uses the same symbols as in
the paper, should be easy enough if you have the paper.

Parallelize the operation of compute_number_cache().

For these functions, the 3d version calls the 2d version which itself calls the
1d version. These operations can all run concurrently. All three include two
loops each over all cells/quads/lines, so there should be plenty to do to
amortize parallel execution.

The only tricky part is that the quad and hex functions accessed a variable
that was first set by the 1d function (number_cache.n_lines). This may now
no longer be available in time for the 2d/3d functions, and so they
need to compute this information themselves. This is cheap, fortunately.
