code: function clean(svgString, options) {
    var aSVGCleaner = new SVGCleaner(options);
    aSVGCleaner.load(svgString);
    return aSVGCleaner.clean().svgString();
  }
docs: This method is to provide a simple interface so one could call `var cleanedSvgString = require('svg-cleaner').clean(svgString, options)`
