Convert a 2-D cell array of strings to a string in MATLAB syntax.

function string = cell2str(cellstr)
%CELL2STR Convert a 2-D cell array of strings to a string in MATLAB syntax.
%   STR = CELL2STR(CELLSTR) converts the 2-D cell-string CELLSTR to a 
%   MATLAB string so that EVAL(STR) produces the original cell-string.
%   Works as corresponding MAT2STR but for cell array of strings instead of 
%   scalar matrices.
%
%   Example
%       cellstr = {'U-234','Th-230'};
%       cell2str(cellstr) produces the string '{''U-234'',''Th-230'';}'.
%
%   See also MAT2STR, STRREP, CELLFUN, EVAL.
