Committing the code that I used last year for this deliverable. Here is
the feedback that I received when I turned it in:

Execution ok but VERY slow. Please check into that - seems significantly
longer than 1 second per floor.

No JUnit testing at all

Javadoc field-level (data member) docs missing, and missing in a few
randomplaces, but ok overall.

Your code is all in one default package. I mentioned at the beginning of
the quarter that I expected the code to properly organized into java
packages.

Good use of accessors/modifiers and error checking.

You have designed/coded your project with everything set up class to
class. All classes are tightly coupled to otther classes. This ignores
much of what we've learned this quarter. What happened to Code to an
Interface, Not to an Implementation? The goal is to create a
well-designed/implemented project here. Remember - code to an interface
not to an implementation.

Execution: 4

Test: 0

Javadoc: 4

OO Coding: 4.5

OO Relationships: 2.5
