Create a defined format for writing profiles

[f-masche]

Inspiration: Mocha

profile('+ vs *', () => {
  let randomNumbers;
  const sum = ([a, b]) => a + b;
  const mult = ([a, b]) => a * b;

  profile('with numbers', () => {
    prepare(() => {
      randomNumbers[0] = Math.random();
      randomNumbers[1] = Math.random();
    });

    execute('sum', sum);
    execute('multiply', mult);
  });

  profile('with strings', () => {
    prepare(() => {
      randomNumbers[0] = Math.random().toString();
      randomNumbers[1] = Math.random().toString();
    });

    execute('sum', sum);
    execute('multiply', mult);
  });

  /* With test data
  prepare(() => getTestData());

  execute('sum', (testData) => {
    const sum = testData[0] + testData[1];
  });
  */
});
