Scrambles/\+Unscrambles a softbit vector. 


\begin{DoxyParams}[1]{Parameters}
\mbox{\texttt{ out}}  & {\em out} & output sbit\+\_\+t array \\
\hline
\mbox{\texttt{ in}}  & {\em in} & input sbit\+\_\+t array \\
\hline
\mbox{\texttt{ in}}  & {\em len} & length of the array to convert\\
\hline
\end{DoxyParams}
The output array can be equal to the input array for in-\/place scrambling/unscrambling
