 * Wrapper for the var_dump function.
 *
 * " The var_dump function displays structured information about expressions
 * that includes its type and value. Arrays are explored recursively
 * with values indented to show structure. "
 *
 * The Var_Dump class captures the output of the var_dump function,
 * by using output control functions, and then uses external renderer
 * classes for displaying the result in various graphical ways :
 * simple text, HTML/XHTML text, HTML/XHTML table, XML, ...
