Stable Release V2
Note: This update contains Break Changes [BC]!
Namespaces of the interface have changed, these are no longer contained in the folder Entity but under the folder Types, also the namespace of the CurrencyConverter has been changed, these are now under Converter\Currencies.
In this update, facades were added for the price calculator and the unit converter. They should help to call the respective classes more simply.
Among other things, a calculation error was fixed that resulted from incorrect rounding.
Furthermore, we have created a discount class and thus make it possible to determine discounts by the total amount.
All changes were tested by several test cases.
