add summary section full width

[eyadsibai]

I tried to add a summary section with full width, but the right side went over the page.

\begin{fullwidth}
\makecvheader

\cvsection{Summary}
xxxxxxxxxxxxxxxxxxxxxxxxxxxxx

\end{fullwidth}```

I added this piece of code

not sure why the full width did not respect the right margin

Use sample-alt.tex as a starting file instead: everything outside the paracol environment is "full width" in this template i.e. do not use fullwidth anywhere in sample-alt.tex.
