Priority file generator. This program will iterate over the complete template tree and build the

priority file from "priority: val" tags found in node.def files. This
    will now allow us to migrate the priority statements found to the specified nodes. Currently the
program does not order the priority nodes according to values (cosmetic
    feature).

        Finally once all the priority values have been migrated to the infected node.defs the priority
program can be added as a postinst hook on debian package install.
