/**
* Text Editor Main Class
*
* This class contains all the main class functions
* EXAMPLE USAGE
*
* $han_editor = new han_editor();
* $han_editor->ipsclass =& $this->ipsclass;
* $han_editor->init();
*
* # To generate the HTML for the editor:
* $editor_html = $han_editor->show_editor( $raw_post, 'Post' );
*
* # $raw_post is either raw HTML for the rich text editor or raw BBCode tagged text when
* # using the standard editor. (See the document on the BBCode parser for more information)
* # 'Post' is the name of the form field you wish use. In this case it'll return $_POST['Post'].
*
* #To process the editor's text into tagged BBCode text:
* $post = $han_editor->process_raw_post( 'Post' );
*
* #'Post' is the name of the form field you used when displaying the editor. As in $_POST['Post']
*
* # To use the HTML generated by editor class for displaying the actual editor (in our example; $editor_html)
* # you'll need to use it like this:
*
*
*
* The form tag MUST have: id='postingform' onsubmit='return ValidateForm()' otherwise the editor will fail.
