Please help with the following:

SpaceStationVisit has an ivar "fuel" that will provide the "getEnergy". We can assume that getEnergy will use fuel directly (i.e. simply return it as-is). Maybe later, we'll do fancy conversions. Instructions:

• Add class named "SpaceStationVisit"
• Have the class implement the "EnergyEventIdea" interface
• Add ivar "fuel" of type "int"
• Add a constructor with one parameter that sets the ivar
• Add getter and setter for ivar
• Add all methods required by implemented interface (also see note above)
