A TimeIt function written in swift based loosely after IPython timeit magic.
In Swift Jupyter Notebook:
%install '.package(url: "https://github.com/bhansconnect/SwiftTimeit", from: "1.0.0")' SwiftTimeit import SwiftTimeit
Use time to measure the execution time of a function once. It is not accurate for short functions.
Use timeit to accurately measure the execution time of a function. Timeit will atomacitically calculate the number of loops to run to get sufficient accuracy, if loops is not specified. Timeit will let you know if there is a large difference between best and worst case execution.
