Create spatial_density.pl

This program requires a configuration file usually specified as spatial_density.conf. The filename is specified on the command line. The code is run as: 
perl spatial_density.pl spatial_density.conf

The code outputs an X Y Z file formatted as:
easting northing density_value

If using opensuse linux, install package perl-PDL using YAST, then install the perl module:
Linear::Algebra module using cpan

The Linear::Algebra module requires the blas and lapack libraries and their corresponding devel packages to be installed (also found as packages in YAST)

Required: the perl module PDL :: Lite 
           the perl module PDL::Basic
           the perl module PDL::MatrixOps
           the perl module PDL::LinearAlgebra 
these modules can all be downloaded and installed using CPAN

If there is no output data then check the file: R-samse.Rout
The R-samse file is an R script and the R-samse.Rout provides information about the SAMSE bandwidth calculated using 'R'.
