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