Class
    Foam::functionObjects::timeActivatedFileUpdate

Description
    Performs a file copy/replacement once a specified time has been reached.

    Example usage to update the fvSolution dictionary at various times
    throughout the calculation:

    \verbatim
    fileUpdate1
    {
        type            timeActivatedFileUpdate;

        libs            ("libutilityFunctionObjects.so");

        writeControl    timeStep;
        writeInterval   1;
        fileToUpdate    "$FOAM_CASE/system/fvSolution";
        timeVsFile
        (
            (-1 "$FOAM_CASE/system/fvSolution.0")
            (0.10 "$FOAM_CASE/system/fvSolution.10")
            (0.20 "$FOAM_CASE/system/fvSolution.20")
            (0.35 "$FOAM_CASE/system/fvSolution.35")
        );
    }
    \endverbatim
