/**
Select2 input. Based on amazing work of Igor Vaynberg https://github.com/ivaynberg/select2.  
Please see [original select2 docs](http://ivaynberg.github.com/select2) for detailed description and options.  
 
You should manually download and include select2 distributive:  

    <link href="select2/select2.css" rel="stylesheet" type="text/css"></link>  
    <script src="select2/select2.js"></script>  
    
To make it **bootstrap-styled** you can use css from [here](https://github.com/t0m/select2-bootstrap-css): 

    <link href="select2-bootstrap.css" rel="stylesheet" type="text/css"></link>    
    
**Note:** currently `autotext` feature does not work for select2 with `ajax` remote source.    
You need initially put both `data-value` and element's text youself:    

    <a href="#" data-type="select2" data-value="1">Text1</a>
    
    
@class select2

/**
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.

For **i18n** you should include js file from here: https://github.com/smalot/bootstrap-datetimepicker/tree/master/js/locales
and set `language` option.
