Question
# Modify the compareCoffeePricesList function and rename
# the function to 'expensesManager'. As the name suggests,
# the 'cafeNameList' should now be used to store a list of expense
# names and it should be renamed to 'expenseNameList' instead. Unlike,
# the cafeNameList, assume that the user will have multiple cost
# entries for the same name. E.g. your expense name lists might
# contain multiple entries called "junk food" and for each there will
# be a corresponding priceList entry for its cost.
#
# Allow the user to see the total cost of an expense with
# the same name. E.g. if the user enters "junk food", your program should
# add the prices of all the priceList entries for "junk food" and
# show the toal. If they enter "coffee" it should show the total for
# coffee expenses, if any are in the list.
