Union of Standard Sets
######################

Syntax
******

   # ``include <cppad/utility/set_union.hpp>``

*result* = ``set_union`` ( *left* , *right* )

Purpose
*******
This is a simplified (and restricted) interface to
the ``std::union`` operation.

Element
*******
This is the type of the elements of the sets.

left
****
This argument has prototype

   ``const std::set<`` *Element* >& *left*

right
*****
This argument has prototype

   ``const std::set<`` *Element* >& *right*

result
******
The return value has prototype

   ``std::set<`` *Element* >& *result*

It contains the union of *left* and *right* .
Note that C++11 detects that the return value is a temporary
and uses it for the result instead of making a separate copy.
