Define displayOrder to display
the name and price of foodItem,
along with its flavor.
The foodItem will be bound to
displayOrder using the bind method.
displayOrder should accept
one argument - the flavor.
Call the bound function displayIceCreamOrder
and
pass "Chocolate" as the argument.
Considering the foodItem in the code below
and
for the flavor "Chocolate",
the bound function should be
"Your order of Chocolate Ice Cream for Rs. 50 is placed."
