03fa7c1431 A complete generic implementation of Binary Space Partitioning Trees (BSP trees) 
has been added. A few specializations of this implementation are also provided
for 1D, 2D and 3D Euclidean geometry. This allows support for arbitrary
intervals sets (1D), polygons sets (2D) and polyhedrons sets (3D) with all
sets operations (union, intersection, symmetric difference, difference, complement),
with predicates (point inside/outside/on boundary, emptiness, other region contained),
with geometrical computation (barycenter, size, boundary size) and with conversions
from and to boundary representation.

556576e645 Fixed initialization of multistep ODE integrators. Relying on the interpolation model of the starter integrator inside only one step was wrong. The model may have a too low order to compute high degrees derivatives in the Nordsieck vector. Now we use several steps and use only grid points instead of interpolated points.
