% HISTORY
%
% 20070601 Added better implementation of \nuparrow, \ndownarrow and
% \bigtimes, all due to Enrico Gregorio
% also made the environment uded inside \NewShadedTheorem
% configurable.
% 20070604 Karl Ove Hufthammer mentioned that mathdesign does not like
% amssymb, and _does_ implement \nleftarrow \nrightnarrow. The
% package option 'noamssymb' now disables loading amssymb
% 20070606 alternative konstruction of \NewShadedTheorem, now using
% ntheorem konstructions internally
% 20070710 bug fix regarding shadedtheorems, the counter aliasing did
% not work correctly
% 20070711 Bug fixed in \ArrowBetweenLines, the \ifin@ should go
% inside the \noalign, not outside.
% 20080617 added \DeclareMathSymbolShorthand and \DeclareMathSet
% 20080618 redesigned and renamed \PullBack to \MoveEqLeft
% 20080828 added better implementation of \MakeDeclareMathSetCommand
% 20100304 updated for latest release

% for making theorems with shaded background
% requires the use of ntheorem, (x)color and framed
% currently only ntheorem is supported (perhaps support for amsthm or
