We're developing a small application to split expenses after a group of friends get together for a reunion. This will track how much each person spent on a particular activity, how much each person owed, and ultimately print out a summary of how much each person owes or is owed.

Use tests to drive your development.

Add to the existing Activity class so that it supports the interaction pattern below.

> require './lib/activity'
# => true

> activity = Activity.new("Brunch")
# => #<Activity:0x007fe4ca1df568 ...>

> activity.name
# => "Brunch"

> activity.participants
# => {}

> activity.add_participant("Jim", 20)
> activity.participants
# => {"Jim" => 20}

> activity.total_cost
# => 20

> activity.add_participant("Joe", 40)
> activity.participants
# => {"Jim" => 20, "Joe" => 40}

Add to the Activity class so that it supports the following interaction pattern. Note, it is assumed that the cost of each activity is split evenly between all participants.

If a participant paid less than their fair share they owe a positive amount.

If a participant paid more than their fair share they owe a negative amount (meaning they are owed money).

> require './lib/activity'
# => true

> activity = Activity.new("Brunch")
# => #<Activity:0x007fe4ca1df568 ...>

> activity.add_participant("Jim", 20)
> activity.add_participant("Joe", 40)

> activity.total_cost
# => 60

> activity.split
# => 30

> activity.owed
# => {"Jim" => 10, "Joe" => -10}

Add to the existing Reunion class so that it supports the interaction pattern below.

> require './lib/reunion'
# => true

> reunion = Reunion.new("Denver")
# => #<Reunion:0x007fe4ca1defc8 ...>

> reunion.name
# => "Denver"

> reunion.activities
# => []

> activity_1 = Activity.new("Brunch")
# => #<Activity:0x007fe4ca1d9438 ...>

> activity_1.add_participant("Jim", 20)
> activity_1.add_participant("Joe", 40)
> reunion.add_activity(activity_1)
> reunion.activities
# => [#<Activity:0x007fe4ca1d9438 ...>]

Add to the existing Reunion class so that it supports the interaction pattern below.

> require './lib/reunion'
# => true

> reunion = Reunion.new("Denver")
# => #<Reunion:0x007fe4ca1defc8 ...>

> activity_1 = Activity.new("Brunch")
> activity_1.add_participant("Jim", 20)
> activity_1.add_participant("Joe", 40)
> reunion.add_activity(activity_1)
> reunion.total_cost
# => 60

> activity_2 = Activity.new("Drinks")
> activity_2.add_participant("Jim", 60)
> activity_2.add_participant("John", 80)
> reunion.add_activity(activity_2)
> reunion.total_cost
# => 200

> reunion.breakout
# => {"Jim"=> 20, "Joe"=> -10, "John"=> -10}

> reunion.print_summary
Jim: 20
Joe: -10
John: -10

Research ERB. Create a template for a webpage using HTML and ERB that will display important details of a Reunion. Create a runner file to create a Reunion with Activities, and use the template to generate an HTML page that you can open in your browser.
