Bar Project - Neil Mithipati

For the exempt method:
    I added a @status instance variable to the Item class, not the Bar class, with a default value of 'available'.      Any time the #exempt method was called that status would change to 'exempt'.

For purchases and most popular methods:
    I added a hash to keep a record of each drink purchased. The key was the drink object itself and the value was a counter that got incremented by one every time it was purchased.
