Overview

Allow customers to expose variables from a template using custom blocks and registers. See github.com/Shopify/liquid/wiki/Liquid-for-Programmers#create-your-own-tag-blocks for more info about blocks. See github.com/Shopify/liquid/wiki/Liquid-for-Programmers#difference-between-assigns-and-registers for info about “registers”, which are used as template-render-specific mutable state (so we can mutate it in the tag/block, then inspect the mutated value after-the-fact).
