[Year 12 SofDev] Use Case

[Mary Ho]

Thanks Mark and Robert,

I always thought a use case for the analysis part would be for the current
system and  then to create another for the design phase for the new
system.  I thought mentor may also be an actor!

Member refers to the people of the group that use the system.  They use
Google for their conversions and calculators.
