  32 =head1 NAME
  33
  34 plugin that shows a table with issues for categories and borrower
  35
  36 =head1 DESCRIPTION
  37
  38 this result is quite complex to build...
  39 the 2D array contains :
  40 * item types on lines
  41 * borrowers types on rows
  42
  43 If no issues are done, the array must be filled by 0 anyway.
  44 So, the script works as this :
  45 1- parse the itemtype table to get itemtype descriptions and set itemtype total to 0
  46 2- for each borrower category :
  47 ** create an array with total = 0 for each itemtype defined in 1
  48 ** calculate the total for each itemtype (SQL request)
  49 The big hash has the following structure :
  50 $itemtypes{itemtype}
  51         ->{results}
  52                 ->{borrowercategorycode} => the total of issues for each cell of the table.
  53         ->{total} => the total for the itemtype
  54         ->{description} => the itemtype description
  55
  56 the borrowertype hash contains description and total for each borrowercategory.
  57
  58 the hashes are then translated to hash / arrays to be returned to manager.pl & send to the template
