Create a Gist as a submission for this activity. Add a README.txt file to the Gist that includes a two to three paragraph explanation in your own words of how self refers to different objects depending on where it is in a Ruby program.


  Self is an interesting object in the Ruby language. Depending on where the self is placed, self can
  actually represent something completely different. If you were to call self on a class method, it means that the class itself can use that method.

for example:

Lithosphere

# In this file we define the methods to help filter out candidates
# This way, we keep these methods separated from other potential parts of the program
class InvalidError < StandardError
end

def find(id)
	unless @candidate.has_key?(:years_of_experience)
		raise InvalidError, 'Candidate must have a :years_of_experience key'
	end
	@candidates.each do |candidate|
