ship: Shift

== Ports ===========================================================
data in:  in
data in:  inShift
data out: out

== Constants ========================================================

== TeX ==============================================================
To Do:
- deal with sign-extension
- rotate (in addition to shift)?
- rotate, shift, and sign-extend subfields of a word?
- scan for lowest/highest bit which is set/clear?
- bitfields crossing two words

== Fleeterpreter ====================================================
    public void service() {
        if (box_in.dataReadyForShip() && box_inShift.dataReadyForShip()) {
            int val = box_in.removeDataForShip();
            int inShift = box_inShift.removeDataForShip();
            if (inShift < 0) val = val >> (-1 * inShift);
            else           val = val << inShift;
            box_out.addDataFromShip(val);
        }
    }
