-    \brief Helper template so that compilation fails if condition is not true.

-    If the condition is true a static function yes is available, othewise the
-    only function available is no().

-    Example for compile time check whether two types are the same:
-    \code
-    IsTrue<is_same<int,int>::value>::yes(); //
-    IsTrue<is_same<bool,int>::value>::yes(); // false, will trigger a compile time error
-    \endcode

-    \code
-    IsTrue<condition>::no()
