# Create a Person named Chris. Chris is allergic to gluten.
# Create a Person named Beth. Beth is allergic to scallops.
# Feed them the following foods
 
pizza = ["cheese", "gluten", "tomatoes"]
pan_seared_scallops = ["scallops", "lemons", "pasta", "olive oil"]
water = ["h", "h", "o"]

chris = Person.new('gluten')

chris.eat(water)

# When a person attempts to eat a food they are allergic to, raise a custom exception
# For example:  AllergyError
 
 
# Bonus: When a person attempts to eat a food they are allergic to,
#        ... remove ALL the food from the person's stomach before raising the exception
