A five-node pyramid, the conforming transition between a hexahedron's face
and tetrahedra: Bedrosian's rational shape functions with a collapsed (Duffy)
Gauss rule, a certified Jacobian on the base square with exact volume, a
scaled Jacobian, C3D5 / CPYRAM / LS-DYNA degenerate solid, VTK_PYRAMID and
the binary mesh code 13. A distorted hex8-pyramid5-tet4 transition mesh
passes the patch test and uniaxial tension exactly.

The image's face names came from one sample per source face (the first
element face's centre), so a source face whose sampled element face was
off it, or a sliver, mapped wrong and the true image face went untagged.
Each source face now maps to the image faces its own reflection covers,
and each element face to the nearest of those.

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.

The bodies' elements are reflected across a datum plane (or a point and
normal) with fieldcraft_mesh::mirror and joined on it. The image is tagged as
the design's body at the reflected place (found by volume and centroid, or
named in `as`), its faces with that body's faces under them, so sets by face
name reach both halves. Half a bar meshed hex8 or hex20 and mirrored has the
whole bar's node and element counts and volume, and its bending deflection to
1e-12; tet4 and tet10 mirror valid and conforming.
