%
% PURPOSE: Insert some onecolumn material in full-width on double-column page.
%
% SHORT DESCRIPTION:
%
% It is denoted to place some material in full-width at any place
% on double-column page (\twocolumn mode). The part of material
% can be placed on the next page. Existing text is placed
% under inserted material in two columns (it is reformatted).
%
% Provides new environment:
%
% \begin{strip} ... \end{strip}
% -----------------------------
%
% Puts \vbox{...} in full-width on double-column page.
% Adds \stripsep glue before and after
% (By default \stripsep=15pt plus2pt minus 2pt).
% It can be problems with floats and footnotes. In the case of
% problems with footnotes it is possible to correct the situation
% using commands \footnotemark and \footnotetext.
%
% Provides new command:
% \oldcolsbreak{#1}
%
% Adds #1 in place of original column break if strip is placed
% on the right column.
