Detailed Description

Comprehensive doctest-based unit tests for element traits and shape functions.

Tests cover: A. ElementTraits data integrity:

1. Basic identification fields (elemType, dim, order, etc.)
2. Standard coordinates consistency
3. Face definitions (GetFaceType, faceNodes)
4. Order elevation (elevatedType, elevSpans, elevNodeSpanTypes)
5. Bisection refinement (numBisect, bisectElements)
6. VTK compatibility (vtkCellType, vtkNodeOrder)

B. Shape function correctness:

1. Partition of unity: sum_j N_j(p) == 1
2. Nodal interpolation: N_i(node_j) == delta_ij
3. First derivative consistency (FD vs analytic)
4. Second derivative consistency (FD of D1)

This is a serial test (no MPI required).
