% CITATION PSIZZL  - citation macros
%
% The first time you cite the reference, use the `=' syntax:
% this creates an entry in the table of references.
% here's how to refer to a reference the first time:
% "...as was shown first in\reference\DrellYan={%
%   Drell,~S.~D., Levy,~D.~J., Yan,~T.~M.,
%   A FIELD THEORETIC MODEL FOR ELECTRON - NUCLEON DEEP INELASTIC
%   SCATTERING,
%   Phys.~Rev.~Lett. \refspec{22, 744-8(1969)}.
%   }%
% here's how to cite the ref:
% "...hadrons produced in this way\cite\DrellYan\ obey a distribution..."
% or:
% "...as was shown first in \reference\DrellYan .  "
% or:
% "...end of sentence. \Reference\DrellYan\ has the somewhat curious.."
% References cited this way will have automatic style switching.
%
% Figures and tables are to be defined in an analogous way
% The first time a figure is referred to:
% "... these data are displayed in
%  \figure\<mnemonic>=
%  {Title of the figure}{caption}{<the figure itself>} more text..."
% and on subsequent references:
% "...the cross section ( see \figure\nanobarn)..."
% or:
% "...end of sentence. \Figure\newcross\ shows how the new physics..."
% Tables are exactly analogous to figures.
%
% Equations are defined:
% \equation\<mnemonic>={<equation expression without $$'s>}%
% e.g.:
% \equation\quadrature={x^2+y^2=z^2}%
% to use this construct:
% "...end of sentence. \Equation\quadrature\ therefore represents..."
