Add functionality for setting observation weights and re-writing the PEST control file.
arbitrary assignment of weight multipliers for groups
assignment of group weight multipliers based on fraction of total phi
assignment of group weight multipliers via interactive slider(s) and a pie chart (and/or printed output)
base (possibly uncertainty-based) weights should be maintained in separate column of obsinfo dataframe (e.g. rename to "base_weight" if necessary). To allow comparison to base weight with successive runs.
Add functionality for setting parameter bounds
by parameter group
we could also include NB examples of how to set par bounds and obs weights arbitrarily by observation using pandas
an additional feature to estimated parameter values relative to bounds would be useful
