counts(*, denoise=False)
  Returns the total number of instructions executed.

  See *FunctionCounts.denoise()* for an explanation of the
  *denoise* arg.

  Return type:
     int

delta(other, inclusive=False)
  Diff two sets of counts.

  One common reason to collect instruction counts is to determine
  the the effect that a particular change will have on the number
  of instructions needed to perform some unit of work. If a change
  increases that number, the next logical question is "why". This
  generally involves looking at what part if the code increased in
  instruction count. This function automates that process so that
  one can easily diff counts on both an inclusive and exclusive
  basis.

  Return type:
     *FunctionCounts*

stats(inclusive=False)
  Returns detailed function counts.

  Conceptually, the FunctionCounts returned can be thought of as a
  tuple of (count, path_and_function_name) tuples.
