You're starting your own web development school called Codebar! Everybody at Codebar -- whether they are attending workshops or teaching them -- is a Member.

• Each member has a full_name.
• Each member should be able to introduce themselves (e.g., "Hi, my name is Kevin!").

Each Member is also either a Student or an Instructor.

• Each student has a reason for attending Codebar (e.g., "I've always wanted to make websites!").
• Each instructor a bio (e.g., "I've been coding in Ruby for 5 years and want to share the love!").
• Each instructor also has a set of skills (e.g., ["Ruby", "Javascript", "C++"]).
• An instructor can gain a new skill using add_skill.

Codebar also has Workshops. Each workshop has...

• A date.
• A classroom.
• A group of instructors.
• A roster of students.

Create an add_participant method that accepts a member attribute. If the Member is a Coach, add them to the coaches list. If a Member is a Student, add them to the students list.

Hint: look into Ruby's .class method.

Create another method print_details that outputs the details of the workshop.

Hint: look into .each_with_index.

Make your code work for the following calls and print out the response you can see in the comments below...

workshop = Workshop.new("12/03/2014", "Shutl")

jane = Student.new("Jane Doe", "I am trying to learn programming and need some help")
lena = Student.new("Lena Smith", "I am really excited about learning to program!")
vicky = Instructor.new("Vicky Ruby", "I want to help people learn coding.")
vicky.add_skill("HTML")
vicky.add_skill("JavaScript")
nicole = Instructor.new("Nicole McMillan", "I have been programming for 5 years in Ruby and want to spread the love")
nicole.add_skill("Ruby")

workshop.add_participant(jane)
workshop.add_participant(lena)
workshop.add_participant(vicky)
workshop.add_participant(nicole)
workshop.print_details
# =>
# Workshop - 12/03/2014 - Classroom: CR6

#    I want to help people learn coding.
# 2. Nicole McMillan - Ruby

The print_details method currently does a number of different things, like printing out workshop details, the list of Students and the list of Coaches.

Create separate methods to print the workshop details (date and classroom), a method to print out the students and one to print out the coaches. Call these from print_details instead of having all the code there.

Also, make sure that these methods cannot be invoked from outside the class.

Hint: look into defining private class methods.
