``sable_init_func''

Initializes global variables (see sable_init_globals) and sets:

• xxml_elements on sable_elements (after saving xxml_elements in sable_previous_elements)
• german_token_to_words on sable_token_to_words (after saving german_token_to_words in sable_previous_token_to_words) if user-selected language is german
• english_token_to_words on sable_token_to_words (after saving english_token_to_words in sable_previous_token_to_words) if user-selected language is not german
  $\Rightarrow$ here, other languages could be treated, too.
  The languages that are used should be the same as in ``set_ttw_functions'' and in ``restore_ttw_functions''.
• token_to_words on sable_token_to_words
