- Todo:
- Needs a bit more error checking and more documentation.
- Idea for Future:
- Generalize to generic vector types. (Does this require reworking the GSL linear fitting routines? Doesn't matter now, the GSL linear fitting routines are now reworked.)
- Idea for Future:
- Possibly create a new gsl_bspline class which replaces the GSL bspline workspace
- Idea for Future:
- Allow user to probe chi squared and the covariance?
