	   *   - 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]:

	   * 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,
