> binding should be aware of at least pageAtached and pageDetached events
> to initialize, or clear contents.
> I've made a binding prefix for zebra effect
> 	<t:grid source="vessels" rowsPerPage="15" t:id="results" rowClass="cycle:line1,line2">
> 	</t:grid>
> the problem was that for every reload the first line would alternate. This is because binding is
> attached to a page instance and is not aware of page's lifecycle.
> I've made a workarround by having a static WeakHashmap tracking pages with this binding,
> and by adding:
> ${cycle:reset}
> at the begining of each page that uses this binding.
> some other bindings may also need to clean resources...
