\usepackage{fancyhdr}   %fucking thing refuses to put headers on page 1
\pagestyle{fancy}

%\usepackage{tocloft}   %???

\usepackage{multicol}
%could instead just use \onecolumn and \twocolumn to switch
%between 1 & 2 column formats, BUT every such switch needs a page break.
%This provides the following environment:
%\begin{multicols}{NumOfColumns}
%[OptionalMultiColumnWideHeader, e.g. \section{The User Interface}]
%YourText
%\end{multicols}
%within this environment floating figures and tables are disabled -
%although * versions (full wide) are allowed, though "h" disabled.
%Also longtable is incompatible with multicols.
%If want vertical line between columns do
%\setlength\columnseprule{.3pt}   %0pt for no line
%Also multicols* environment same except in last page, no flush column
%ends; instead all white space is concentrated in last column.
%Multicols can occasionally put footnotes on wrong page (you will
%be warned if it is worried); put \pagebreak in strategic places to
%fix that.
