* TODO:
* - factorize the onbegin/onend code
* in smilTimeItem and smilTimeContainer_generic
* - support complex event-values (event + time offset)
* - add a decent onDOMReady() for IE<9
* - fix the repeatCount/repeatDur stuff
* - fix the 'begin' behaviour in 'seq' containers
* - redesign EVENTS to make it compatible with bean.js
* - propose timesheets.js as jQuery / YUI modules
