ITP - files - simple_file.txt

To create a file in Ruby, we pass the name of the file and the mode we
want to assign to File.new. Fire up irb if you haven't already and enter
the following:

 irb :001 > my_file = File.new("simple_file.txt", "w+")
 => #<File:simple_file.txt>
irb :002 > my_file.close
