Add processing parameters

The list of processing parameters are:

1)Which pipelines to use -- any user combination of grenades_fastproc, grenades_parallelproc, EDNAproc, autoProc, XDSapp etc

2)For all pipelines, a common way to specify:

    A reference HKL file
    Statistics program (MRFANA for now)
    High Resolution cutoff
        Isotropic or Anisotropic 
        A user selectable combination of metrics with some logical grouping if possible. e.g. (Completeness >90) AND (I/SigI >1 OR CC0.5>30%). I think for the short -medium term this will only be a simple AND relationship though
            metric (I/sigI, CC0.5,Rmeas,% etc), value 

    Binning:
        Number of bins
        Number of reflections per bin
        Binning mode: 
            Equal-volume
            Equal-observation-number
            1/d**2

3)For a selection of pipelines (only fastproc and parallelproc for the moment):

    Should we run Molecular replacement from user model
        if so - a place for complexes/models like before (this is one of the overlaps with sample information)
    Molecular replacement from unit cell
    Automatic SAD
        If so, anomalous element, how many, proteins sequence (could be from sample information instead of processing plan)
