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
