AngularJS renaming exercise

rename_angular_parts

Because I think the hardest part of getting started with AngularJS is it's esoteric names, I'm suggesting the following replacements of the AngularJS terminology.

scope -> state

factory -> data/models

filter -> helper

directive {restrict: 'E'} -> custom_tag
directive {restrict: 'A'} -> custom_attribute

transclude -> layout

directive#require ^ -> require_controller
directive#require -> require_sibling

isolated scope -> new_state
  & -> expression
  @ -> value
  = -> two_way

directive#link -> init
compile -> compile_template
