script to administer the budget periods table
 This software is placed under the gnu General Public License, v2 (http://www.gnu.org/licenses/gpl.html)

 ALGO :
 this script use an $op to know what to do.
 if $op is empty or none of the above values,
	- the default screen is build (with all records, or filtered datas).
	- the   user can clic on add, modify or delete record.
 if $op=add_form
	- if primkey exists, this is a modification,so we read the $primkey record
	- builds the add/modify form
 if $op=add_validate
	- the user has just send datas, so we create/modify the record
 if $op=delete_confirm
	- we show the record having primkey=$primkey and ask for deletion validation form
 if $op=delete_confirmed
	- we delete the record having primkey=$primkey
 if $op=duplicate_form
  - displays the duplication of budget period form (allowing specification of dates)
 if $op=duplicate_budget
  - we perform the duplication of the budget period specified as budget_period_id
