// way, it'll receive the node for `x[1]` already parsed, and wraps

 * following attributes:
 *
 *   - version: Which version of the source map spec this map is following.
 *   - sources: An array of URLs to the original source files.
 *   - names: An array of identifiers which can be referrenced by individual mappings.
 *   - sourceRoot: Optional. The URL root from which all sources are relative.
 *   - sourcesContent: Optional. An array of contents of the original source files.
 *   - mappings: A string of base64 VLQs which contain the actual mappings.
 *   - file: Optional. The generated file this source map is associated with.
 *
 * Here is an example source map, taken from the source map spec[0]:
 *

/**
 * An IndexedSourceMapConsumer instance represents a parsed source map which
 * we can query for information. It differs from BasicSourceMapConsumer in
 * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
 * 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.
 *
 *  {
 *    version : 3,
 *    file: "app.js",
 *    sections: [{
 *      offset: {line:100, column:10},
 *      map: {
 *        version : 3,
 *        file: "section.js",
 *        sources: ["foo.js", "bar.js"],
 *        names: ["src", "maps", "are", "fun"],
 *        mappings: "AAAA,E;;ABCDE;"
 *      }
 *    }],
 *  }
