/*
* Returns the percent change from the original to the desired servings.
* The percent is expressed as a decimal. i.e.:
* 1 = 100%
* 0.5 = 50%
* 1.5 = 150%
* If either of the serving values is 0, a value of 1 serving is assumed.
*
* To calculate the number of servings, the following formula is used:
*
* Desired Servings =
* | Desired Servings / Original Servings | - 0.1 *
* (1 - | Original Servings / Desired Servings | ))
*
* where | x | is the absolute value of x
*
* original - number of servings the recipe was designed for
* desired - the number of servings wanted
*
* returns the % change that should apply to all of the ingredients.
