Network.PublicSuffixList.Create
Description
This script parses the public suffix list, and constructs a data structure which can
be used with the isSuffix function in Lookup.hs. It exports a GSink which produces
the opaque DataStructure and can be fed any Source as input.
This makes an few assumption about the information in the public suffix list: namely, that no rule is a suffix of another rule. For example, if there is a rule abc.def.ghi then then is no other rule def.ghi or !def.ghi
The actual data structure involved here is a tree where the nodes have no value and the edges are DNS labels. There are two trees: one to handle the exception rules, and one to handle the regular rules.
