   * input.
   *
   * The only parameter is a raw source map (either as a JSON string, or already
   * parsed to an object). According to the spec for indexed source maps, they
   * have the following attributes:
   *
   *   - version: Which version of the source map spec this map is following.
   *   - file: Optional. The generated file this source map is associated with.
   *   - sections: A list of section definitions.
   *
   * Each value under the "sections" field has two fields:
   *   - offset: The offset into the original specified at which this section
   *       begins to apply, defined as an object with a "line" and "column"
   *       field.
   *   - map: A source map definition. This source map could also be indexed,
   *       but doesn't have to be.
   *
   * Instead of the "map" field, it's also possible to have a "url" field
   * specifying a URL to retrieve a source map from, but that's currently
   * unsupported.
   *
   * Here's an example source map, taken from the source map spec[0], but
   * modified to omit a section which uses the "url" field.
