/**********************************************************************
John and his family went to 5 different restaurants. The bills were
$124, $48, $268, $180 and $42. John likes to tip 20% of the bill when
the bill is less than $50, 15% when the bill is between $50 and $200,
and 10% if the bill is more than $200.

Implement a tip calculator using objects and loops:
1. Create an object with an array for the bill values
2. Add a method to calculate the tip
3. This method should include a loop to iterate over all the paid bills
and do the tip calculations
4. As an output, create 1) a new array containing all tips, and 2) an
array containing final paid amounts (bill + tip).


EXTRA AFTER FINISHING: Mark's family also went on a holiday, going to 4
different restaurants. The bills were $77, $375, $110, and $45. Mark
likes to tip 20% of the bill when the bill is less than $100, 10% when
the bill is between $100 and $300, and 25% if the bill is more than $300
(different than John).

5. Implement the same functionality as before, this time using Mark's
tipping rules
6. Create a function (not a method) to calculate the average of a given
array of tips.
7. Calculate the average tip for each family
8. Log to the console which family paid the highest tips on average
