Issue: http://issues.qcadoo.org/browse/QCADOOMES-310
Brief
This functionality introduces a new entity: transformation. A transformation binds multiple consuption transfers as inputs and multiple production transfers as outputs.
While developing this we also have to change the behavior of transfers a little. Depending on the transfer type we should have the following restrictions:
- consumption - we cannot enter the To stock area
- production - we cannot enter the From stock area
We should also remove the transformation type.
