Replaces the Java CoHDS with CGAL::Surface_mesh<Point3> (Simple_cartesian
kernel). Adds domain-specific property maps for lambda/theta/idx/alpha and
face geometry type — the direct C++ equivalent of CoVertex/CoEdge adapters.
New files:
include/conformal_mesh.hpp — ConformalMesh type + property-map helpers
include/mesh_builder.hpp — mesh factories (triangle, tetrahedron,
quad-strip, fan) for tests and examples
tests/cgal/ — second test executable (conformallab_cgal_tests)
built only with -DWITH_CGAL=ON
Test results (local, -DWITH_CGAL=ON):
conformallab_tests: 36 registered | 23 passed | 13 skipped | 0 failed
conformallab_cgal_tests: 14 registered | 14 passed | 0 skipped | 0 failed

Implements getEuclideanCircleFromHyperbolic() in C++ (hyperboloid model
→ Poincaré disk via Lorentz boost + circumcircle). Ports the 2 Java tests
that were the only remaining candidates not requiring HDS or a solver.
All other unported tests (DataTypesTest, SchottkyIOTest,
UniformizationDataTest, BranchedCoverTorusTest) are blocked by XML
serialization or HDS – stubs remain for Phase 4.
Test totals: 36 registered | 23 passed | 13 skipped | 0 failed.

Fully ported (pure math, no HDS required):
test_discrete_elliptic_utility.cpp – 2 tests
normalizeModulus: move tau into SL(2,Z) fundamental domain
test_p2_utility.cpp – 3 tests
P2 projective geometry (perpendicularBisector, pointFromLines,
makeDirectIsometryFromFrames double vs long double precision)
New headers:
include/discrete_elliptic_utility.hpp – normalizeModulus
include/p2_utility.hpp – P2 Euclidean geometry (templated
on scalar type so double and long double share one implementation)
Stubs (GTEST_SKIP, blocked until HDS port – Phase 4):
test_hyper_ideal_functional.cpp – 5 tests (1 @Ignore in Java)
test_hyper_ideal_hyperelliptic_utility.cpp – 3 tests
test_spherical_functional.cpp – 5 tests
All use CoHDS + HalfEdgeUtils which are not yet ported to C++.
Result: 34 tests total | 21 passed | 13 skipped | 0 failed

- include/matrix_utility.hpp: 4x4 mapping matrix R·from=to (Eigen)
- include/projective_math.hpp: dehomogenize, hyperbolicDistance,
isOnSegment (collinearity + betweenness via 3D cross/dot),
getPointOnCorrespondingSegment (parameter by arc-length ratio)
- test_matrix_utility.cpp: port of MatrixUtilityTest (1 test)
- test_surface_curve_utility.cpp: port of SurfaceCurveUtilityTest
testIsBetween and testGetPointOnSegment_SegmentEdge (2 tests)
- tolerance adjusted to 1e-12 for matrix inversion (2.7e-15 rounding
from Eigen vs jReality's LU; both well within meaningful accuracy)
Total: 16/16 tests pass

- Add Google Test via CMake FetchContent (v1.14.0)
- Add clausen.hpp: Clausen integral, Lobachevsky function, Im(Li2)
- Add hyper_ideal_utility.hpp: generalized and ideal-vertex hyperbolic
tetrahedron volume formulas using Eigen for the 4x4 Gram determinant
- Port ClausenTest (5 tests) and HyperIdealUtilityTest (8 tests) from
Java/JUnit — all 13 pass with same tolerances as the Java originals
- Fix pre-existing VIEWER/viewer case mismatch in CMakeLists.txt
