word2number looking for your specific language with

1. defined environment variable w2n.lang with ISO lang code like en, hi, de and if not found
2. over locale.getdefaultlocale() and if not found
3. over environment variable "LANGUAGE" and if not found
4. fallback to english 

Place in the data directory your language specific dictionary file with ISO lang code in the name.
