Make datepicker customizable

[ghetolay]

Hi,

Datepicker is complicated ui element because everybody wants to render it differently. You just have to look at all the implementations available. For me none fits, I would need a mix of different approach. We could just take your issue #52 about year control, some does not need it, some wants double arrow and I'm more for a dropdown menu.

With angular 2 and ng-content I think we should be able to create a component flexible enough to cover all needs. I'm thinking about a DatePickerCore with a good API to be manipulated, a minimal static template and using multiple <ng-content> for the rest of the template. Then we could create some of the most common datepicker on top of that core (DatePickerMinimal, DatePickerFull) and for uncommon users like me, they could still create their own component based on DatePickerCore.

I could start working on yet another datepicker plugin but, if you are up to it, I would rather rally with you so we could build a good and flexible datepicker plugin for once.

@ghetolay that sounds like a perfect idea, really. unfortunately I am really busy lately, but if you are prepared to contribute on this one I can add you to the repo and you develop this on a separate branch. that would be awesome.

@jkuri Yep no problem let's do it.

How should we proceed to discuss about specs ? Is opening issues ok ?

[jkuri]

yes, that should be fine I think
