Functions
HRESULT	TissueForge::space_init (struct space *s, const FPTYPE *origin, const FPTYPE *dim, FPTYPE *L, FPTYPE cutoff, const struct BoundaryConditions *bc)
	Initialize the space with the given dimensions.
int	TissueForge::space_getsid (struct space *s, struct space_cell **ci, struct space_cell **cj, FPTYPE *shift)
	Get the sort-ID and flip the cells if necessary.
HRESULT	TissueForge::space_shuffle (struct space *s)
	Run through the cells of a #space and make sure every particle is in its place.
HRESULT	TissueForge::space_shuffle_local (struct space *s)
	Run through the non-ghost cells of a #space and make sure every particle is in its place.
HRESULT	TissueForge::space_growparts (struct space *s, unsigned int size_incr)
	Grow the parts allocated to a #space.
HRESULT	TissueForge::space_addpart (struct space *s, struct Particle *p, FPTYPE *x, struct Particle **result)
	Add a #part to a #space at the given coordinates. The given particle p is only used for the attributes, it itself is not added, rather a new memory block is allocated, and the contents of p get copied in there.
HRESULT	TissueForge::space_addparts (struct space *s, int nr_parts, struct Particle **parts, FPTYPE **xparts)
int	TissueForge::space_get_cellids_for_pos (struct space *s, FPTYPE *x, int *cellids)
HRESULT	TissueForge::space_del_particle (struct space *s, int pid)
HRESULT	TissueForge::space_update_style (struct space *s)
HRESULT	TissueForge::space_prepare_tasks (struct space *s)
	Prepare the tasks before a time step.
HRESULT	TissueForge::space_prepare (struct space *s)
	Prepare the space before a time step.
HRESULT	TissueForge::space_getpos (struct space *s, int id, FPTYPE *x)
	Get the absolute position of a particle.
HRESULT	TissueForge::space_setpos (struct space *s, int id, FPTYPE *x)
	Set the absolute position of a particle.
HRESULT	TissueForge::space_flush (struct space *s)
	Clear all particles from this #space.
HRESULT	TissueForge::space_flush_ghosts (struct space *s)
	Clear all particles from the ghost cells in this #space.
struct task *	TissueForge::space_addtask (struct space *s, int type, int subtype, int flags, int i, int j)
	Add a task to the given space.
HRESULT	TissueForge::space_verlet_init (struct space *s, int list_global)
	Initialize the Verlet-list data structures.
int	TissueForge::space_gettuple (struct space *s, struct celltuple **out, int wait)
	Get the next free #celltuple from the space.
int	TissueForge::space_getcell (struct space *s, struct space_cell **out)
	Get the next unprocessed cell from the spaece.
int	TissueForge::space_verlet_force (struct space *s, FPTYPE *f, FPTYPE epot)
	Collect forces and potential energies.
HRESULT	TissueForge::space_releasepair (struct space *s, int ci, int cj)
	Free the cells involved in the current pair.
