mesh.size.set adds a size control on faces, bodies, a box or a sphere;
mesh.size.growth sets the growth rate; mesh.size.clear and
mesh.size.list. The tet mesher bakes the controls into its graded field,
the hex meshers, cells and the octree take the graded RegionSize, and
the block projection and mesh plans divide their edges by it.

With "transition": "pyramid" (the default; "tie" keeps the old join) a tet
cell is meshed after the hex cells, with a pyramid on every hex face of its
cuts and its tetrahedra on the pyramids' sides: one conforming mesh, no tie.
Where it cannot be built the cell says why (no_pyramids) and is tied. The
apex height is 0.4 of the quad's edge, so pyramids on faces meeting at a
right angle do not cross.

Every tied interface between cells of one design body carries `why`: the tet cell (and why
auto fell back), the reason the body's cells did not sweep together, or the cell meshed alone
by its method; so an agent knows which cut or method to change.

A node on the secondary surfaces of two ties (a chip's underside and its
sides, a cut face and an outer face) got one constraint per tie. When the
main nodes of one follow the other's main surface, the second constraint is
nearly the first again, and eliminating it divided by round-off: the Pi 5
heat model put 21.9 W more in than its 8 W. Such a node now follows the
main faces of all its ties together (balanced to 5e-11 of the power), a
node following a node that follows it back (a tie each way on one
interface) is an error naming both ties, and a tie row that still nearly
repeats the constraints before it is an error naming them.
mesh.cells ties one way by a fixed order of the cells (hex main to tet)
and makes one tie per tied cell, tie_<cell>, replacing the ties an earlier
run made, so its own ties never hold a node twice.

hex_mesh_swept_cells lays out one cross-section for several cells: every
cell's walls (its cut faces included) are imprinted together, every cell's
levels are levels of all, one interval assignment and one set of layers,
and each region of each level interval is filled by the cell it lies in.
Cells meet node for node across every cut, T-junctions included.
mesh.cells sweeps the cells of each design body together first and meshes
cell by cell only what does not sweep together (saying why); the reply
gives every cell's volume, scaled Jacobian and edge ratio.

The extrusion's automatic cross-section blocks reach both commands; the
half crank arm, cut only on its symmetry plane, meshes all-structured
(sJ >= 0.37) with no seeds either way, and mesh.hex.generate's
description says so.

mesh.tet.generate and mesh.planar stacked a second mesh on a meshed body;
mesh.hex.*, mesh.hex.octree and mesh.cells wiped every body's mesh. All of
them, and mesh.mirror for its image bodies, now go through replace::clear:
the body's old elements and the nodes only they use go, other bodies stay.
The reply reports replaced {body, elements, nodes}, stale_sets (sets that
listed the old labels) and results_cleared; the command is one undo step.
replace::MESHERS names the bodies each mesher fills, and replacement()
says what a run would replace, for the app to ask first. mesh.block stays
additive: a body is built from several blocks. Refs #267.

The ~40 parameter checks give a ProblemKind instead of text; Session::execute looks the problem
up in the command's form (a group's missing field becomes that field's own path). Replies still
name keys; forms phrase the same problem by label. A test refuses every field of every form and
checks each refusal names a field of that form.

mesh.tet.generate, mesh.hex.*, mesh.hex.blocks and mesh.cells give every
seed on the open design to their meshers, which match them to their own
curves by position, so a seed on an edge two cells share holds in both. The
tet reply gives, per seed, the mesh edges along it. Docs and the roadmap
say what is honoured where.
Fixes#230.

Each cell (a body of the open design) gets its own method: structured hex where
one fits (auto falls back to tet and says why), or tet. All go into one mesh.
Cells on either side of a partition are joined: where their element faces
match node for node the nodes are merged; otherwise (hex next to tet, or
different divisions) the two partition faces get a set each and a dual mortar
tie, the reported hex-tet transition. A 40 mm bar cut in half, one half hex,
the other tet, stretches F L / (E A) to 1e-6.
