/*
  INSTRUCTIONS
  =============================================================
  In this kata you are required to, given a string, replace every letter with its position in the alphabet.

  If anything in the text isn't a letter, ignore it and don't return it.

  a being 1, b being 2, etc.

  As an example:

  alphabet_position("The sunset sets at twelve o' clock.")
  Should return "20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11" as a string.
