Third Look at AList

This assignment once again builds on the previous, this time with the addition of the Filter and FilterTest classes. The former compares the input number to the numbers in the list and responds with those elements in the list less than the input given. The latter was our first look at JUnit testing, of which I found to be very useful and is something that I will definitely be using in future projects. All required tasks to be performed on the list required by the specification were implemented successfully.
