-- Filters documentation
 
Preamble:
    Into the version 2.1.2 a new "filters function" was introduced. 
    It permit to specify what data can be or cannot be view by the user
    Now it use a simple text file (.ini style) for define the rules, but in the
    future, it'll load them from a db, so it can have a centralize use
 
Usage:
    Into the config directory, you'll find a filters.conf file (if not, open hylapex
    and it'll create a new one for you, with the standard configuration)
    Open the file with your preferred text editor, you'll see a section filters 
    ( [filters] ) with four fields inside:
    - case_sensitive, 
    - filter_list_done, filter_list_recv, filter_list_send
    case_sensitive control if I'll make the control for the data in case sensitive manner or not
    filter_list_* control what column will be effected by the filter. 
    For specify the filter, you need to add a new section with the "view" name, a "_" and the 
    column number where set the filter. Into it, you can add the field not_view or only_view
    and the text to filter
    
Example:
    Here I set filters.conf so the user can:
    - On done view not see the row, on the object column, where are present
        the "invoice" string
    - On the done view only see the rows where "michele" are present on the
        "owner" column
    - On the receive view, only see the row where the "My customer id" are
        present on the  "Sender id" column
    
    [filters]
    filter_list_done = 3, 4
    filter_list_send =
    filter_list_recv = 2
    case_sensitive = 0

    [done_3]
    not_view = invoice
    
    [done_4]
    only_view = michele
    
    [recv_2]
    only_view = My customer id
