Define a class with a class method "find"
Usage
Apple.find("macintosh")
class Apple
def self.find(variety)
code goes here
end
end
Same as above but notice the lack of self prefix before the method name
Usage
Apple.find("macintosh")
class Apple
class << self
def find(variety)
code goes here
  end
end
end
