Introducing a "LazyUnweightedEvaluation": the computation of the model
and Jacobian are deferred until one or the other is actually accessed.
Class "LocalMultivariateJacobianFunction" replaces the anonymous class
that was created when calling the "model" method.
The "evaluate" method of "LocalLeastSquaresProblem" instantiates either
"UnweightedEvaluation" or "LazyUnweightedEvaluation", as requested by
the user of the "create" factory method.

Make QR the default in GaussNewtonOptimizer
...
Theoretically QR offers the best blend of speed and numerical stability.
Empirically the QR implementation is slightly faster than the Cholesky
implementation.

Since the normal matrix is symmetric positive (semi-)definite, the

Make QR in GaussNewton faster and more accurate
...
Re-factored the code in GaussNewtonOptimizer so that the decomposition
algorithm sees the Jacobian and residuals instead of the normal
equation. This lets the QR algorithm operate directly on the Jacobian
matrix, which is faster and less sensitive to numerical errors. As a
result, one test case that threw a singular matrix exception now passes
with the QR decomposition.
The refactoring also include a speed improvement when computing the
normal matrix for the LU decomposition. Since the normal matrix is
symmetric only half of is computed, which results in a factor of 2 speed
up in computing the normal matrix for problems with many more
measurements than states.

BSP tree now provide an API to compute a global signed distance.
...
The distance is defined from a test point to the region. It is positive
if the point is outside of the region, negative if the point is inside,
and zero when the point is at the boundary. The distance is continuous
everywhere, so it can be used with a root solver to identify accurately
boundary crossings. This API is available for all BSP trees, in
Euclidean and spherical geometries, and in all dimensions.
