-Adjust factor when the given factor times the persons comes gives a faction of a person.  For example, if a recipe serves three and the factor is 1/2.  Since we can't have a recipe that serves 1 1/2, the persons is rounded up to two and the factor is then adjusted to 2/3. -Don't allow bogus input like negative servings -Correctly round persons when scaling by factor
