Adding a percentage to productIngredientType #85
Description
productIngredientType is used by the activeIngredients array in the productResource for specifying the ingredients in a product.
productIngredientType currently contains just an id of the ingredient (specified as a scheme and id) and a name for the ingredient.
It is proposed to add a percentage property to productIngredientType so that it is possible to specify the amount of each ingredient in the product.
