Details:

Attached is a patch to add bspline derivative evaluation capabilitiles to
bspline/.  Please, if possible, include this functionality in the gsl-1.12
release.

Included in the patch are...
 - Evaluation of arbitrary order bspline derivatives
 - Rework of existing bspline evaluation to support efficient derivative
computation
 - Derivative-related unit tests for 'make check'
 - Documentation updates to doc/bspline.texi

The patch applies (patch -p1 from the toplevel directory), compiles, and runs
'make check' cleanly against HEAD using gcc 4.2.4.  Compilation includes with
-ansi -Wall -pedantic -DGSL_RANGE_CHECK.  Existing gsl_bspline.h type
signatures were not modified, but three new methods were added:
gsl_bspline_eval_nonzero, gsl_bspline_eval_deriv,
gsl_bspline_eval_deriv_nonzero.

Please ensure bspline/TODO removes the derivative item after the patch. 
bspline/Changelog will need to be updated-- I did not do so in the patch. 
Sorry, I'm new to git.

Please email with any questions/issues.

- Rhys Ulerich
