% headings text into te header. Must do more trickery to get toc entry.

%

%
% Let subsubsections be listed in the table of contents.

%
%% Bibliography / References
%% -------------------------
%

% Change to `References' since this is more appropriate for a thesis.
\providecommand\refname{References}% only exists with babel
\providecommand\bibname{}% make sure it exists
\renewcommand\bibname{\refname}
% The above won't work with babel, not even with \AtBeginDocument, because babel
% redefines \bibname with every language change.
% The following only works for one/some language(s) (bad), and wipes other
% definitions (worse):
\newcommand\bibisrefname{\renewcommand\bibname{\refname}}
\AtBeginDocument{\def\extrasUKenglish{\bibisrefname}}

% Provide a command which suppresses the automatic insertion of space by an
% immediately following \cite command when the cite package is loaded with
% option "adjust" (which is default). This des nothing when option "noadjust" is
% active.
\providecommand\citenoadjust{\hskip0.000009pt\relax}

% Bibliography style.
% This can't currently be overridden by the document, for example when the use
% has a more sophisticated plain style, other than by e.g. copying the other
% style as plain.bst into the document's directory. A class option to suppress
% this \bibliographystyle would be better.
\bibliographystyle{unsrt}



%
%% Column Balancing
%% ----------------
%

% Balance columns on last page. Use between paragraphs, or between words.
\newcommand\columnbreak{%
    \unskip
    \raggedbottom
    \pagebreak[4] \relax % without this space, words are run together
