- NOTE 1       : Special Orders can have two types of discounts simultaneously:
                   1.- On each component of the order (raw product)
                   2.- Occasional discount OR Client discount. Occasional discount only for the current
                       transaction ( prepayment, completing the order ) if you need on BOTH is needed to
                       add the occasional discount on each stage (prepayment, completing the order)
- NOTE 2       : Groups can have two types of discounts simultaneously:
                   1.- On the group product (the container).
                   2.- Occasional discount OR Client discount.
                 Group price and tax is calculated based on its components, at the needed moment.
                 The group has a Price-drop that is a discount % applied on each of its components. This is
                 used to calculate the group price and tax. For this reason, the group price, cost and taxes
                 are not editable on squeeze.

                 will need to run the "fix_roles.sql" script in the lemonpos/database_resources/ folder.
                 The symptom for running the fix_roles.sql script is that the "admin" user will be rejected as
                 an administrator, but you still login lemon with these user to sell things, but not for apply
                 occasional discounts or remove items or configure lemon ( unless LowSecurity mode is activated).
