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
