 /*
 Instructions:

 Load the plugin using:

  	$this->load->plugin('js_calendar');

 Once loaded you'll add the calendar script to the <head> of your page like this:

 <?php echo js_calendar_script('my_form');  ?>

 The above function will be passed the name of your form.

 Then to show the actual calendar you'll do this:

 <?php echo js_calendar_write('entry_date', time(), true); ?>
 <form name="my_form">
 <input type="text" name="entry_date" value="" onblur="update_calendar(this.name, this.value);" />
 <p><a href="javascript:void(0);" onClick="set_to_time('entry_date', '<?php echo time(); ?>')" >Today</a></p>
 </form>


 Note:  The first parameter is the name of the field containing your date, the second parameter contains the "now" time,
 and the third tells the calendar whether to highlight the current day or not.

 Lastly, you'll need some CSS for your calendar:

 .calendar {
 	border: 1px #6975A3 solid;
 	background-color: transparent;
 }
 .calheading {
 	background-color: #7C8BC0;
