/**
* 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, ...
