%% USER MACRO
% --------------------------------------------------------------------------------------------------
% auxiliary macro to construct the layout of each cell in the Periodic Table of Elements
% \pgfPTbuildcell(<lines>,<columns>)[<entries>]
% or
% \pgfPTbuildcellstyle{name}(<lines>,<columns>)[<entries>]
% each entry is constructed according to the structure <line>|<line_i>-<line_f>;<column>|<column_i>-<column_f>;<what>
% OUTPUT:
% \pgfPT@cellcontents -> a comma separated list.
% --------------------------------------------------------------------------------------------------
% Each entry stores the following data: (contents::csstring::coordinate+wd+ht)
% The coordinate corresponds to the right upper corner "x+y"
% \global\pgfPT@cellcontentssize -> size of the list
% Example of use (the default layout for each cell in the Periodic table):
%   -------------
%   | 1 | 2 | 3 |  line 1
%   -------------
%   | 1 | 2 | 3 |  line 2
%   -------------
%   | 1 | 2 | 3 |  line 3
%   -------------
%   | 1 | 2 | 3 |  line 4
%   -------------
%   | 1 | 2 | 3 |  line 5
% \pgfPTbuildcell(5,3)[% 5 lines x 3 columns
%        (1;1-2;z),(1;3;radio),% line 1; the atomic number spreads over column 1 and 2
%        (2-3;2;cs),(4;2;name),% lines 2 and 3, line 4
%        (5;2;ar)% line 5
