      *  Parse the GET parameters in the URL bar into an Object, mapping keys
      *  to values. Will not behave properly on repeated keys.

+     *  key1=value1&key2=value2 (standard GET syntax)
+     *  nestedKey1:nestedValue1;nestedKey2:nestedValue2 (custom extension)

      *  The Object has a toString() method which returns the parameters in the
      *  same format as `window.location.search`.
