/*
* HOW TO USE
* ==========
*
* You can assign the data you which to dump in two ways:
* a) when creating an object, e.g.
* $d = new dump ( $my_data )
*
* b) by calling the method assign()
* $d = new dump;
* $d->assign( $my_data );
*
* The method get_html() will return an HTML-table representing the
* data which has been assigned before using one of the methods mentioned
* above. After either a) or b) a command like
* echo $d->get_html ();
* would output the table.
*
* CUSTOMIZING
* ===========
*
* The output is formatted using HTML-inline-styles which are defined in the
* properties style_key, style_value and style_type. By assigning different
* values output may be changed easily to fit individual needs.
*
* REQUIREMENTS
* ============
*
* This class needs PHP 4.0.2 or later to run; by removing the call to the
* function get_ressource_type () it can be used on PHP 4.0.0. Just follow
* the comment to do the change
*
* TODO
* ====
*
* - method for generating raw output
* - interface for customizing styles
*
