Added copier class to this lab from what I created in class
renaming stuff
still moving stuff
cleaning code up
futzing with enums
still deciding how this should work.  I think the two interfaces are going to be tiprates and tip calculator, although the variables make this tricky.  Still messing with structure of the program.
got my structure down, using all classes so no code needs to be modified in the program.  The tricky part is the bag calculator needs to have more variables passed in than the restaurant calculator, but the different classes solve for this.
decided not to have separate classes for bags
Now it's getting fun, I'm reusing the reader class :D
Doing more cool stuff, have the startup class mostly done.
mostly done, everything is interchangeable now.
starting on challenge 3
created first working version
my code was surprisingly similar to the sample answer.  I had not looked at it until now.  Changed just a few things and added some comments.  All done..
