Check Splitter

check-splitter.rb

# New CheckSplitter objects should have an attribute that stores the total cost
# of the meal. They should have a way to define the tip amount (and a value
# that's set by default). They should be able to define how many people are in
# the group. They should use that information to help determine how much each
# person owes.
