var parse_params = function(url){
  var pairs = url.match(/\/?\??(.*)/)[1].split('&');
  var out = [];
  pairs.forEach(function(chunk){
    var keyvalues = chunk.split('=');
    for(var i=0; i<keyvalues.length; i++){
      if(i % 2 === 0){
        var obj = {};
        obj[keyvalues[i]] = keyvalues[i + 1]
        out.push(obj);
