PROG: Fixed ProcessExportPds4 attribute ordering problem in unitTest.

    // Remove the schema from the lable because we cannot ensure that

    // attributes come out in the same order every time

    std::cout << p.StandardPds4Label().toString().remove(QRegExp("xmlns.*\""));

    QString rawLabel = p.StandardPds4Label().toString();

    rawLabel.remove(QRegExp(" xmlns.*=\".*\""));

    rawLabel.remove(QRegExp(" xsi.*=\".*\""));

    std::cout << rawLabel;

    std::ofstream ofs;

    p.OutputLabel(ofs);

    p.StartProcess(ofs);

    std::cout << p.GetLabel().toString().remove(QRegExp("xmlns.*\""));

    rawLabel = p.GetLabel().toString();

    rawLabel.remove(QRegExp(" xmlns.*=\".*\""));

    rawLabel.remove(QRegExp(" xsi.*=\".*\""));

    std::cout << rawLabel;

    p.WritePds4("temp.img");

    remove("temp.img");
