TextParser.js

/**
 * A simple parser that emulates the style of remark-parse, but will only
 * parse plain text, not markdown.
 *
 * Can be used to implement redaction and restoration in a non-markdown context
 *
 * Is currently implemented by taking remark-parse and removing unwanted
 * functionality; be aware that could have unexpected side effects, and we may
 * at some point in the future want to reimplement this by starting from
 * scratch.
