Functions

	Name	Description
int	add_edge ( int A, int B, int GID )
int	AllocateEdgeGroup()
int	append_new_split_vertex ( int A, int B )
int	append_vertex_internal()
int	AppendEdge ( int v0, int v1, int GID )
int	AppendEdge ( const FIndex2i& ev, int GID )
int	AppendEdge ( const FEdge& E )
bool	CheckValidity ( EValidityCheckFailMode FailMode )	This function checks that the graph is well-formed, ie all internal data structures are consistent
EMeshResult	CollapseEdge ( int VKeep, int VRemove, FEdgeCollapseInfo& Collapse )
void	debug_check_is_edge ( int E )
void	debug_check_is_vertex ( int V )
bool	edge_has_v ( int EID, int VID )
int	edge_other_v ( int EID, int VID )
int	EdgeCount()
edge_iterato...	EdgeIndices()
value_iterat...	Edges()	Enumerate edges.
int	FindEdge ( int VA, int VB )
FEdge	GetEdge ( int EID )
int	GetEdgeGroup ( int EID )
FIndex2i	GetEdgeV ( int EID )
int	GetMaxVtxEdgeCount()

bool	IsJunctionVertex ( int VID )
bool	IsRegularVertex ( int VID )
bool	IsVertex ( int VID )
int	MaxEdgeID()
int	MaxGroupID()
int	MaxVertexID()	These values are (max_used+1), ie so an iteration should be < MaxVertexID, not <=
EMeshResult	RemoveEdge ( int EID, bool bRemoveIsolatedVertices )
EMeshResult	RemoveVertex ( int VID, bool bRemoveIsolatedVertices )
int	replace_edge_vertex ( int EID, int VOld, int VNew )
void	SetEdgeGroup ( int EID, int GroupID )

vertex_itera...	VertexIndices()
FSmallListSe...	VtxEdgesItr ( int VID )	Enumerate edge ids connected to vertex (i.e. edge one-ring)
FSmallListSe...	VtxVerticesItr ( int VID )	Enumerate "other" vertices of edges connected to vertex (i.e. vertex one-ring)
