Hex templates

This is my collection of Hex templates. I have now also added all edge templates, ladder creation templates, and interior templates from Matthew Seymour's book, David King's list of Hex templates, and HexWiki. Thanks to Eric Demer, Mason Mackaman, Comonoid, and Bobson8 for suggesting templates. See here for the naming scheme used for templates on this page. The filenames are subject to change.
