 compile time + runtime interface.
 
 These are functors which provide runtime support for preforming regular masking

+operations with complie time composed masks. The reasoning behind creating functions
+which create a mask on compile time and that mask would then be applied to some
+integral type T at a later time.

                 Compile + run time set interface.
 All masks should be hidden unless one is supplied as a template parameter?
 however the internal mask created will be availiable always its just that the user
 may not want to actually see it or have to use it themselves.

 {
-    void operator() ( T::value_type& bits );
+    template <typename T>

+example usage for something like this could be:

+typedef set_bit< 3 > set_third_bit;

+unsigned int some_integer(0);
+set_third_bit()(some_integer);

+this would the third bit of the some_integer would then be set.
