‎Ladder creation templates on the 6th row: Added a new template

Selinger: /* Ladder creation templates on the 4th row */ Added a template. Not sure if the amount of space shown is exactly right; the ladder can start further to the right, but I think it's equivalent to it starting where shown.

-There is not yet a [[naming of templates|naming convention]] for ladder generation templates, so all examples on this page are currently unnamed. Like edge templates, we classify ladder generation templates by the row on which the connecting stone is located, rather than by the kind of ladder it generates. In fact, some templates generate more than one ladder, for example a 4th row ladder going left or a 3rd row ladder going right. In an attempt to avoid confusion, we say "ladder generation template on the 3rd row", rather than "3rd row ladder generation template", to indicate that the template is a 3rd row template (but may, for example, generate a 2nd row ladder).

-On [http://www.drking.org.uk/hexagons/hex/templates.html David King's Hex template page], ladder generation templates are called "cascading templates". However, they should not be confused with what [http://www.mseymour.ca/hex_book/hexstrat.html Matthew Seymour's book] calls "cascading ladders", which is a different concept.

 When checking the templates, keep in mind that the templates do not in general guarantee that Red will get the indicated ladder. They only guarantee that Red will get at least the indicated ladder (or a better one) if Red doesn't connect to the edge outright.
