Classes
struct	SpacePoint4SSVFT
	SpacePoint definition to be used for the unit tests. Implements all the relevant methods. More...

Functions
double	getRndDouble (std::mt19937 &gen, double from, double to)
	Provides random double number between $from and $to.

int	getRndInt (std::mt19937 &gen, int from, int to)
	Provides random integer number between $from and $to.

std::vector< double >	makePlaneFromTriplet (SpacePoint4SSVFT aa, SpacePoint4SSVFT bb, SpacePoint4SSVFT cc)
	Calculates equation of the plane (alphax + betay + gamma*z + delta = 0), given the three points.

	BOOST_AUTO_TEST_CASE (single_seed_vertex_finder_small_planes_test)
	Unit test for SingleSeedVertexFinder. Fits a set of the spacepoints with planes and compare the result to the easy-to-calculate expected result.

	BOOST_AUTO_TEST_CASE (single_seed_vertex_finder_small_rays_test)
	Unit test for SingleSeedVertexFinder. Fits a set of the spacepoints with straigh lines and compare the result to the easy-to-calculate expected result.

	BOOST_AUTO_TEST_CASE (single_seed_vertex_finder_full_planes_test)
	Unit test for SingleSeedVertexFinder. Generates real-looking sets of the spacepoints, then fits them with planes, finds a vertex, and then verifies the reconstructed vertex is actually near the original one.

	BOOST_AUTO_TEST_CASE (single_seed_vertex_finder_full_rays_test)
	Unit test for SingleSeedVertexFinder. Generates real-looking sets of the spacepoints, then fits them with rays, finds a vertex, and then verifies the reconstructed vertex is actually near the original one.
