+/*!
+ * Converter that rearranges bits in an integer.
+ *
+ * Conversion is reduced to a minimal number of mask & shift operations at compile-time. 
+ *
+ * Usage:
+ *
+ *  bitset_converter&lt;&gt; is an empty converter list (cannot be used without adding at least one mappings).
+ *  (list)::add::map&lt;from, to&gt maps the from'th input bit to the to'th output bit.
+ *
+ *  Convenience function to add a continous region of mappings:
+ *  bitset_converter&lt;&gt;::add::value&lt;to2&gt; is equivalent to bitset_converter&lt;&gt;::add::map&lt;0, to2&gt;
+ *  (list)::add::map&lt;from, to&gt::add::value&lt;to2&gt; is equivalent to ::add::map&lt;from, to&gt::add::map&lt;from + 1, to2&gt;
+ *
+ *  Inut bits without a corresponding "from" entry are ignored.
+ *  Output bit without a corresponding "to" entry are always zero.
+ *
+ *  The same input/output bit can appear in multiple mappings.
+ *
+ *  Invoke the converter: (list)::convert(integer)
+ *
+ * Limitations:
+ *
+ *  Input bits must fit in a native integer type provided by in_types::bits&lt;bits&gt;.
+ *
+ *  Output bits must fit in an integer type selected by out_types::bits&lt;bits&gt;.
+ *
+ * Example:
+ *
+ *  // Create a converter that swaps the first two bits, keeps the next one and ignores all others.
+ *  typedef bitset_converter<>::add::map<0, 1>::add::map<1, 0>::add::value<2> Converter;
+ *
+ *  // Convert something.
+ *  Converter::convert(3);
+ *
