Add finer grain hooks

[tmpvar]

• start (first chance)
  • matcher (string ".{name}, #{name}, :input[type={name}]")
  • match (it would be nice if this were a css selector, if possible)
  • extract (this is called when the template is cloned)
  • apply (apply data into the cloned template)
  • insert (insert the template back into the document)
• done (last chance)
