This is a small helper class to be used with \helpref{wxCriticalSection}{wxcriticalsection} 
objects. A wxCriticalSectionLocker enters the critical section in the
constructor and leaves it in the destructor making it much more difficult to
forget to leave a critical section (which, in general, will lead to serious
and difficult to debug problems).

Example of using it:

\begin{verbatim}
void Set Foo()
{
    // gs_critSect is some (global) critical section guarding access to the
    // object "foo"
    wxCriticalSectionLocker locker(gs_critSect);

    if ( ... )
    {
        // do something
        ...

        return;
    }

    // do something else
    ...

    return;
}
\end{verbatim}

Without wxCriticalSectionLocker, you would need to remember to manually leave
the critical section before each {\tt return}.
