       This module is designed to extract information from Nessus NBE files. Functions have been designed to
       return certain sets of data, such as service banners and OS versions. Other functions have been provided
       that will return more specific information, such as all IPs listening on a given port or all IPs
       associated with a specified plugin id.

       To obtain a list of banners

               my @banners =  nbanners(@nessusdata);
               print @banners;

               # returns
               IP|service banner

               # example
               192.168.0.5|CompaqHTTPServer/2.1

               # returns
               IP|specified port

               # example
               192.168.0.5|ssh (22/tcp)

               # 2 returns medium severity vulnerabilities
               # 3 returns low level security notes

               my @countvulns = nstatvulns(@nessusdata,1);
