There are concerns that the current Stokes I fitting code may not be the best currently available (since it's based on the FORTRAN MINPACK-1 package from 1980). Some experimenting is needed to determi…

Currently, we are using double precision. Consider having the option of:
1. exporting multiple precisions
2. specify the precision via preprocessor flag
For 2, I usually would do something like t…
