+ * \file
+ * \brief Concept checks for the Boost Range library.
+ *
+ * The structures in this file may be used in conjunction with the
+ * Boost Concept Check library to insure that the type of a function
+ * parameter is compatible with a range concept. If not, a meaningful
+ * compile time error is generated. Checks are provided for the range
+ * concepts related to iterator traversal categories. For example, the
+ * following line checks that the type T models the ForwardRange
+ * concept.
+ *
+ * \code
+ * function_requires<ForwardRangeConcept<T> >();
+ * \endcode
+ *
+ * An additional concept check is required for the value access
+ * property of the range. For example to check for a
+ * ForwardReadableRange, the following code is required.
+ *
+ * \code
+ * function_requires<ForwardRangeConcept<T> >();
+ * function_requires<
+ *     ReadableIteratorConcept<
+ *         typename range_iterator<T>::type
+ *     >
+ * >();
+ * \endcode
+ *
+ * \see http://www.boost.org/libs/range/doc/range.html for details
+ * about range concepts.
+ * \see http://www.boost.org/libs/iterator/doc/iterator_concepts.html
+ * for details about iterator concepts.

+            Collection traits provide uniform access to different types of 
+            collections. This functionality allows to write generic algorithms
+            which work with several different kinds of collections.
+
+            Currently following collection types are supported:
+                - containers with STL compatible container interface ( see ContainerConcept )
+                    ( i.e. \c std::vector<>, \c std::list<>, \c std::string<> ... )
+                - c-style array 
+                   ( \c char[10], \c int[15] ... )
+                - null-terminated c-strings
+                    ( \c char*, \c wchar_T* )
+                - std::pair of iterators 
+                    ( i.e \c std::pair<vector<int>::iterator,vector<int>::iterator> )
+
+            Collection traits provide an external collection interface operations.
+            All are accessible using free-standing functions.
+
+            The following operations are supported:
+                - \c size()
+                - \c empty()
+                - \c begin()
+                - \c end()
+
+            Container traits have somewhat limited functionality on compilers not
+            supporting partial template specialization and partial template ordering.

+            An \c iterator_range delimits a range in a sequence by beginning and ending iterators. 
+            An iterator_range can be passed to an algorithm which requires a sequence as an input. 
+            For example, the \c toupper() function may be used most frequently on strings, 
+            but can also be used on iterator_ranges: 
+            
+            \code
+                boost::tolower( find( s, "UPPERCASE STRING" ) );
+            \endcode
+
+            Many algorithms working with sequences take a pair of iterators, 
+            delimiting a working range, as an arguments. The \c iterator_range class is an 
+            encapsulation of a range identified by a pair of iterators. 
+            It provides a collection interface, 
+            so it is possible to pass an instance to an algorithm requiring a collection as an input.
