This sample shows how to automatically replace all <textarea> elements
		with a CKEditor instance by using a JavaScript call.
	
		To replace a <textarea> element, place the following call at any point
		after the <textarea> element or inside a <script> element located
		in the <head> section of the page, in a window.onload event handler:
	
CKEDITOR.replace( 'textarea_id' );
		Note that textarea_id in the code above is the id attribute of
		the <textarea> element to be replaced.
