This duck is not ready yet...

List of @tags to support

------------------------

* @class - OK

* @extends - OK

* @singleton - OK

* @cfg - OK

* @constructor - OK

* @property

* @type

* @method - OK

* @event - OK

* @param - OK

* @return - OK

* @member

* @static

* @link

* @ignore @hide - these probably do exactly the same thing.

* @private - this is also almost the same, with the possibility that

  documentation could also be generated so, that it includes private

  methods, in which case stuff marked with @private is included,

  while @ignore and @hide are never included.

Some usage stats from ExtJS source:

* @hide 306 times

* @private 199 times

* @ignore 11 times.

* @namespace - Looks useless to me and indeed ExtJS source doesn't use

  it at all.
