[Halld-tagger] End user polarization

[dugger at jlab.org]

Mark,

I'm less interested in how I will use the information than how others want
to use the information. Recently, we started talking about code that can
be implemented by the end user. I think that it makes sense to hear what
other people may want.

Take care,
Michael
