  #
  # [+fname+]  That name of the file
  # [+path+]   Specifying true mean fname contains the full path.
  #     The default, false, uses Server.public_root as the path.
  #
  # [+return+] true on success, false on failure
  #
  # === Examples
  #
  # require 'nitro/cgi/send_file'

  # class MyController < Nitro:Controller
  #   def download(fname)
  #     send_file(fname)
  #   end
  # end
  #
  # class MyController < Nitro:Controller
  #   def download()
  #     send_file('/etc/password', true)
  #   end
  # end
