  27 =head1 DESCRIPTION
  28
  29 Is used for callnumber computation.
  30
  31 If the user send an empty string, we return a simple incremented callnumber.
  32 If a prefix is submited, we look for the highest callnumber with this prefix, and return it incremented.
  33 In this case, a callnumber has this form : "PREFIX 0009678570".
  34  - PREFIX is an upercase word
  35  - a space separator
  36  - 10 digits, with leading 0s if needed
