lementation Details</h2>
		<ul>
			<li>
				Some bugs in the assignment operator implementations and in <b>reset</b>
			have been fixed by using the "copy and swap" idiom.
			<li>
				Assertions have been added to check preconditions of various functions; 
				however, since these use the new <a href="../../boost/assert.hpp">&lt;boost/assert.hpp&gt;</a>
			header, the assertions are disabled by default.
			<li>
				The partial specialization of <b>std::less</b> has been replaced by <b>operator&lt;</b>
