New GSL extension for multi-dimensional least squares fits

[Patrick Alken]

Hi all,

  I have made a new GSL extension library to aid in multi-dimensional
least squares fits (ie: when your observations depend on more than
one variable). It can be tricky to construct the least squares matrix
X when you have 3 or higher dimensions in your model, so this extension
is designed to make it very simple to construct the matrix.

  It is located at:

  http://ucsu.colorado.edu/~alken/gsl/ndlinear-1.0.tar.gz

and includes texi documentation in doc/ as well as an example program
with plots of the results.

I welcome any feedback. Brian - could you add a link for this to
the GSL page?
