\section{Zuul bad}





\section{Zuul better v1}

\subsection{printLocationInfo}

This code duplication has been previously avoided with the printRoomInfo()
method.
It has been renamed to printLocationInfo(), as part of the commit e52a34789, to
match the exercise.

\subsection{getExit}

The exit attributes have been made private and a getter was added in commit
53c427ff3. A switch statement has been used instead of multiple if statements.

\subsection{getExitString}

This method has been added as part of commit ca65af2e2.

\subsection{HashMap, setExit}

Room exits are now stored in an HashMap since commit c9d890b9b. The setExits()
method has been replaced by setExit() which takes advantages of the HashMap.
