/**
 * Better GI than print_r or var_dump -- but, unlike var_dump, you can only dump one variable.  
 * Added htmlentities on the var content before echo, so you see what is really there, and not the mark-up.
 * 
 * Also, now the output is encased within a div block that sets the background color, font style, and left-justifies it
 * so it is not at the mercy of ambient styles.
 *
 * Inspired from:     PHP.net Contributions

 *
 * @param mixed $var  -- variable to dump
 * @param string $var_name  -- name of variable (optional) -- displayed in printout making it easier to sort out what variable is what in a complex output
 * @param string $indent -- used by internal recursive call (no known external value)
 * @param unknown_type $reference -- used by internal recursive call (no known external value)
