/**
Combodate input - dropdown date and time picker.    
Based on [combodate](http://vitalets.github.com/combodate) plugin (included). To use it you should manually include [momentjs](http://momentjs.com).

    <script src="js/moment.min.js"></script>
   
Allows to input:

* only date
* only time 
* both date and time  

Please note, that format is taken from momentjs and **not compatible** with bootstrap-datepicker / jquery UI datepicker.  
Internally value stored as `momentjs` object. 

@class combodate
@extends abstractinput
@final
@since 1.4.0
@example
<a href="#" id="dob" data-type="combodate" data-pk="1" data-url="/post" data-value="1984-05-15" data-original-title="Select date"></a>
<script>
$(function(){
    $('#dob').editable({
        format: 'YYYY-MM-DD',    
        viewformat: 'DD.MM.YYYY',    
        template: 'D / MMMM / YYYY',    
        combodate: {
                minYear: 2000,
                maxYear: 2015,
                minuteStep: 1
           }
        }
    });
