View source for Shelf Craft Reform

Shelf crafting reform is in progress.  The introduction of forms is intended as an intermediate stage in the crafting recipe.  However, the detail as to how to actually transform a form into a shelf is still not yet defined. 

=== Considerations ===

* Should be sufficiently intuitive for new players to discover reasonably quickly
* Keep material costs balanced and comparable to existing recipe
* Not tedious or painful to execute repeatedly, consider steps and time
* Not easy to trigger accidentally when not intending to craft, or when using components for other normal use-cases
* Need things to exhibit consistent and logical behavior, i.e. avoid unexpected corner cases

Should we expect forms to be primarily general storeboxes, i.e. right-clicking with an item preferentially places the item in the box consistent with other storeboxes?  Or should they be special-purpose things that merely ALSO function as a storebox in some circumstances, e.g. some right-clicking is crafting?  Or maybe we should disallow right-click/punch access entirely and only allow items to fall through?

=== Ideas for Shelf Recipes ===

'''(using wood shelves as example then extrapolate to others)'''

* Right-click on a form with a plank (excess stays in inventory)
* Place any planks in a form (excess stays in shelf)
* Must place exactly 1 plank inside a form
* Place planks inside a form and pummel (how to prevent taking planks out?)
* Place a plank against a form
* Place plank against a form and pummel it into the form
* Place a form between a plank above and below (could consume 0 to 2 of those planks)
* Pummel a form while between a plank above and below (probably don't need to consume planks)
* Pummel a form wielding a plank
* Place a wooden mallet head inside a form (looks more shelf-board-shaped) by right-click
* Pummel a form wielding a wooden mallet head
* Pummel a form with a plank or mallet head inside wielding a stone stylus (as a tool)
* Place a "peg" (stick) on top of form with plank in it and pummel it into the form
* Pummel a frame while surrounded by appropriate planks to make a shelf instead of form
