This module exposes functions to produce statistics on function calls
val v : counter_names:string list -> tcreates a handle for function call statistics. The optional argument can be used to create named additional internal counters to keep track, for instance, of the size of the inputs. Use to only use the default counter that keeps track of the number of function calls
val increment : t -> string -> int -> unitincr t name n increments the named counter with name name of t by n units
val tic : t -> unitPlay the internal clock
val tac : t -> unittac t n pauses the internal clock of t. Must follow a tic.
val get_count : ?name:string -> t -> intNumber of tic-tacs if no name is provided, else the counter associated to name
val get_span : t -> Mtime.spanTotal time taken by tic-tacs
