/// \brief Set Type Specification
/**
This struct is used to specify an unordered_set specification.
It is not a container, it is just a metaprogramming facility to
express the type of a set. Generally, this specification will
be used in other place to create a container.
It has the same syntax that an tr1::unordered_set instantiation,
except that the allocator cannot be specified. The rationale behind
this difference is that the allocator is not part of the
unordered_set type specification, rather it is a container
configuration parameter.
The first parameter is the type of the objects in the set, the
second one is a Hash Functor that takes objects of this type, and
the third one is a Functor that compares them for equality.
Bimap binding metafunctions can be used with this class in
the following way:
\code
using namespace support;
BOOST_STATIC_ASSERT( is_set_type_of< unordered_set_of<Type> >::value )
BOOST_STATIC_ASSERT
(
is_same
<
unordered_set_of<Type,HashFunctor,EqualKey>::index_bind
<
KeyExtractor,
Tag
>::type,
hashed_unique< tag<Tag>, KeyExtractor, HashFunctor, EqualKey >
>::value
)
typedef bimap
<
unordered_set_of<Type>, RightKeyType
> bimap_with_left_type_as_unordered_set;
BOOST_STATIC_ASSERT
(
is_same
<
unordered_set_of<Type>::map_view_bind
<
member_at::left,
bimap_with_left_type_as_unordered_set
>::type,
unordered_map_view
<
member_at::left,
bimap_with_left_type_as_unordered_set
>
>::value
)
\endcode

This struct is similar to unordered_set_of but it is bind logically to
a relation. It is used in the bimap instantiation to specify the
desired type of the main view. This struct implements internally
a metafunction named bind_to that manages the quite complicated
task of finding the right type of the set for the relation.
