Critical bug at Slice

[walterxie]

In Slice, the method below is alway returning the 1st element of a parameter, even if the parameter has multiple dimensions:

    public double getArrayValue() {
        return functionInput.get().getArrayValue(0);
    }

The correct code should be

    public double getArrayValue() {
        return functionInput.get().getArrayValue(indexStart);
    }
