	barnes_hut_solver.hpp
	The hierarchical solver: the same physics as direct summation, with most of the interactions replaced by an approximation whose error is bounded and measured.
	direct_kernel.hpp
	The innermost loop of the direct solver, in more than one instruction set.
	direct_solver.hpp
	Direct summation: every particle against every other, and the standard the rest of the project is measured against.
	force_solver.hpp
	What every gravitational force solver in this project provides.
	interaction_count.hpp
	The unit in which the cost of a force evaluation is reported.
	morton.hpp
	The order the tree solver reads particles in, and the reason it is not the order they arrived in.
	octree.hpp
	The tree the Barnes-Hut solver walks, and the moments it carries.
	reference_kernel.hpp
	The acceleration of one particle, computed as accurately as this project knows how, so that a fast kernel's error can be measured rather than asserted.
	sycl_direct_solver.hpp
	Direct summation on the integrated GPU.
	sycl_tree_solver.hpp
	The Barnes-Hut traversal on the integrated GPU, which is the hardest thing this project asks of the device.
	tree_walk.hpp
	The traversal that turns a tree into an acceleration, which is where a Barnes-Hut solver spends nearly all of its time.
