                        BUG: Motor.export_eng doesn't work for liquid motors
Describe the bug
Take a look the method's definition. As the liquid motors do not have propellant grains, this method will fail.
To Reproduce
Create a liquid motor and try to export its data using export_eng method
Expected behavior
- We should refactor this method and ensure that it work for
- We should also create unit tests to prevent this behavior to happen again (please include all the types of motor in this test, even the GenericMotor)
Screenshots
Working on it right now
