Make consoleio class have named params
user
```ruby
require 'io/console'
class ConsoleIO

  attr_reader :input
  attr_reader :output

  def initialize(input: STDIN, output: STDOUT)
    @input = input
    @output = output
  end

  def clear_screen
    # ANSI control sequences, see http://www.termsys.demon.co.uk/vtansi.htm
    beginning_of_line = "\e[H"
    erase_screen    = "\e[2J"
    print_text beginning_of_line + erase_screen
  end

  def get_char
    c = @input.getch
    raise Interrupt if c == "\u0003"
    raise EOFError if c == "\u0004"
    c
  end

  def print_text(text)
    @output.print text
    @output.flush
  end

  def print_newline
    print_text "\n"
  end

  def print_text_with_newline(text)
    print_text text + "\n"
