	Please read this before copying the toolbar:

	* One of the best things about this widget is that it does not impose any styling on you, and that it allows you 
	* to create a custom toolbar with the options and functions that are good for your particular use. This toolbar
	* is just an example - don't just copy it and force yourself to use the demo styling. Create your own. Read 
	* this page to understand how to customise it:
    * https://github.com/mindmup/bootstrap-wysiwyg/blob/master/README.md#customising-
