  29 =head1 DESCRIPTION
  30
  31 This plugin is based on authorised values INVENTORY.
  32 It is used for stocknumber computation.
  33
  34 If the user send an empty string, we return a simple incremented stocknumber.
  35 If a prefix is submited, we look for the highest stocknumber with this prefix, and return it incremented.
  36 In this case, a stocknumber has this form : "PREFIX 0009678570".
  37  - PREFIX is an upercase word
  38  - a space separator
  39  - 10 digits, with leading 0s if needed
