You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: example.rb
    path of file: ./repos/rspec_api_documentation/lib/rspec_api_documentation
    
    the code of the file until where you have to start completion: module RspecApiDocumentation
  class Example
    attr_reader :example, :configuration

    def initialize(example, configuration)
      @example = example
      @configuration = configuration
    end

    def method_missing(method_sym, *arg
    
    def remap_headers(requests, key, headers_to_include)
      return requests unless headers_to_include
      requests.each.with_index do |request_hash, index|
        next unless request_hash.key?(key)
        headers = request_hash[key]
        request_hash[key] = headers.select{ |key, _| headers_to_include.map(&:downcase).include?(key.downcase) }
        requests[index] = request_hash
      end
    end
