batch mode: read in censoring flags

[aappling-usgs]

this issue should wait for #143. once we know what format loadflex will use for censored data, we need to read flagged data from csvs into the loadflex format as part of the batch mode script

[aappling-usgs]

see #125 for info on how ANA plans to describe censored data

[aappling-usgs]

as part of this issue, pass censored data to rloadest (loadReg2) using smwrQW format as required (i think! check.) by rloadest

[aappling-usgs]

David's reference just above is for this line in summarizeModel.loadReg:

r.squared = loadReg.fit$RSQ, # R-square needs to change when censored values are present!! see print.loadReg.R line 131 in rloadest. is this adjusted?

which we need to remember to deal with especially when we add in censoring.
