	 * input.
	 *
	 * The first 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;"
	 *      }
	 *    }],
	 *  }
	 *
	 * The second parameter, if given, is a string whose value is the URL
	 * at which the source map was found.  This URL is used to compute the
	 * sources array.
	 *
	 * [0]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit#heading=h.535es3xeprgt

	 *   - 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 first 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;"
	 *      }
	 *    }],
	 *  }
	 *
	 * The second parameter, if given, is a string whose value is the URL
	 * at which the source map was found.  This URL is used to compute the
	 * sources array.
	 *
	 * [0]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit#heading=h.535es3xeprgt
