  25 =head1 DESCRIPTION
  26
  27 This plugin is based on authorised values INVENTORY.
  28 It is used for stocknumber computation.
  29
  30 If the user send an empty string, we return a simple incremented stocknumber.
  31 If a prefix is submited, we look for the highest stocknumber with this prefix, and return it incremented.
  32 In this case, a stocknumber has this form : "PREFIX 0009678570".
  33  - PREFIX is an upercase word
  34  - a space separator
  35  - 10 digits, with leading 0s if needed
