Message:

Changes to the analysis package to add a few more model functions. Documentation and XOPs are to follow later.

General n-point gaussian quadrature has been added to GaussUtils? by including a Gauss-Laguere point generator from Numerical Recipes. See the Paracrystal models for an example, since they needed more than the 76 point quadrature.
