\section{Related Work}
\label{sec:related_work}
%==============================================================================

This section should present related work in the field. All the papers
you are using and building upon should appear here and be described in
a small paragraph. There should normally not be any figures in this
section. Descriptions are also rather unusual, but may be helpful.
