2.2.1 (2/1/2008)
If var-cov becomes singular in BFGS method, we will use estimates from simplex method

2.2 (12/26/2007)
We should not use absolute tolerance in simplex method; set abs.tol to -DBL_MAX to prevent early exit in nelder_mead.c

2.0 (12/7/2007)
Removed dependence on GSL; uses R BLAS libraries for linear algebra routines

1.1 (10/6/2007)
Windows binary now available. However, user will have to download gsl and gslcblas dlls and put them on the path for mlegp to load
