% BOXIT
%
% Use \boxit{ text } to surround text / paragraphs / anything in a
%         box. For example, typing \boxit{the} would produce
%                            +---+
%                            |the|
%                            +---+
%         (you may want to use \strut inside the argument if the
%         boxit is on a line by itself).
