Reimplement problematic NR SLIM-curve routines

[curtis]

In partnership with  Paul Barber at Oxford, we are developing a library of curve routines for combined spectral lifetime data, called  SLIM-curve. Paul originally wrote these routines for his  TRI2 program.

We are looking to release SLIM-curve as a separate open-source library, but there are licensing issues with a few functions which are based on code from  Numerical Recipes—specifically, these functions:

• gaussj
• jacobi
• gammln
• gcf
• gser
• gammp
• mrqmin

As such, we need to recode them using an alternative implementation or from scratch. Libraries possibly useful in this endeavor include the  GNU Scientific Library and the  Flanagan Java Scientific Library.

Aivar, what's the status of this work? Most if not all is complete, right?

This work is done, with some remaining issues that are being tracked in the LOCI trac:
