Implement Layer and Wire alignment

[ftouchte]

Implement wire and layer alignment

• Create 2 CCDB tables
  • /geometry/alert/ahdc/layer_alignment, upstream and downstream corrections
  • /geometry/alert/ahdc/wire_alignment , correction relative to the layer alignment, for now all values are set to zeros
• Make AlertDCFactory to read these tables
• Store the residual_LR in AHDC::hits, our alignment observable
• Fix issue: for the AHDC hits the Kalman filter, we should use the non calibrated ADC

Things of particular importance: I have modified the detectorChanged() method in order to load the new tables, is it the right way to do that?

Bug in AlertDCWireIdentifier(int,int,int) (File: [AlertDCWireIdentifier.java:34-39]):

public AlertDCWireIdentifier(int _sector, int _layer, int _component) {
        sector = _sector;
        layer = _layer;
        component = _layer;
        num = slc2wire(_sector, _layer, _component);
    }

component is assigned _layer

I can't say if this is correct or not:

    public void detectorChanged(int run) {
        factory = (new AlertDCFactory()).createDetectorCLAS(new DatabaseConstantProvider(run,"default"));
        DatabaseConstantProvider cp = new DatabaseConstantProvider(run, "default");
        cp.loadTable("/geometry/alert/ahdc/layer_alignment");
        cp.loadTable("/geometry/alert/ahdc/wire_alignment");
        AHDCdet = (new AlertDCFactory()).createDetectorCLAS(cp);
    }

I guess @baltzell needs to look into that.

Thank you @mathieuouillon, I've fixed the bug in the constructor.

@mathieuouillon this DatabaseConstantProvider initialization paradigm for geometry is around and used in coatjava.
