Using the \protect to solve the \cite and \ref issues
I was having problems using \cite and \ref commands in conjunction \added and \deleted commands from the changes package.
I couln't find a solution in the manual or in a quick search in google, so I am posting a solution here.
Just use the \protect command like
\protect\ref{key}
May work for other commands also. It is not a optimal solution but it works by now.
I still don't have a solution for commands like \section, e.g.
\deleted{\section{Something interesting}}
does not work.
