PHP Reference Debug is a very simple class providing static methods to check whether
or not a variable is a reference .It also allows to get a a more precise value of the
reference count than the PHP debug_zval_dump.The package is written in pure PHP and
has no dependency.
Remarks: the first argument of the methods must always be get_defined_vars to really
and properly defined the scope of the checked variable.(see the how to use example)
