* New treap-based containers: treap, treap_set, treap_multiset.

Browse Source 
*  Corrected compilation bug for Windows-based 64 bit compilers.
*  Corrected exception-safety bugs in container constructors.
*  Updated documentation to show rvalue-references funcions instead of emulation functions.

//! treap_algorithms provides basic algorithms to manipulate
//! nodes forming a treap.
//!
//! (1) the header node is maintained with links not only to the root
//! but also to the leftmost node of the tree, to enable constant time
//! begin(), and to the rightmost node of the tree, to enable linear time
//! performance when used with the generic set algorithms (set_union,
//! etc.);
//!
//! (2) when a node being deleted has two children its successor node is
//! relinked into its place, rather than copied, so that the only
//! pointers invalidated are those referring to the deleted node.
//!
//! treap_algorithms is configured with a NodeTraits class, which encapsulates the
//! information about the node to be manipulated. NodeTraits must support the
//! following interface:
//!
//! <b>Typedefs</b>:

//!
//! <tt>node_ptr</tt>: A pointer to a node
