val reset : t -> unit: empty the graph and shrink it to its initial size

val create : int -> t: create n makes an empty graph with initial capacity n which grows as required

val n_procs : t -> int: number of procedures in graph

val mem : t -> int -> bool: is an int id the index of a node in the graph?

val mem_procname : t -> IR.Procname.t -> bool: is there a node for procname in the graph?

val flag : t -> IR.Procname.t -> unit
val flag_reachable : t -> IR.Procname.t -> unit: flag all nodes reachable from the node of the given procname, if it exists

val iter_unflagged_leaves : f:(Node.t -> unit) -> t -> unit: iterate over all leaves that have their flag set to false

val remove : t -> IR.Procname.t -> unit
val to_dotty : t -> string -> unit: output call graph in dotty format with the given filename in results dir

val add_edge : t -> pname:IR.Procname.t -> successor_pname:IR.Procname.t -> unit: add an edge from pname to successor_pname in the graph, creating a node for pname if there isn't one already

val create_node : t -> IR.Procname.t -> IR.Procname.t list -> unit: create a new node with edges from pname to successor_pnames in the graph

val fold_flagged : t -> f:(Node.t -> 'a -> 'a) -> 'a -> 'a: perform a fold over the nodes in the graph with flag set to true

val default_initial_capacity : int: reasonable minimum capacity for the graph that is prime
