    This functionObject writes a cloud position and in ASCII.
 
    Example of function object specification:
    \verbatim
    cloudWrite1
    {
        type            dataCloud;
        libs            (lagrangianFunctionObjects);
        writeControl    writeTime;
        writeInterval   1;
        cloud           myCloud;
        field           d;
    }
    \endverbatim
