/*!\brief Compiler specific patch for nested template disambiguation.
 * \ingroup util
 *
 * The WALBERLA_TEMPLATE is a patch for the Microsoft Visual C++ compiler that does not correctly
 * parse definitions of nested templates of the following form:

   \code
   template< typename T >
   class Alloc {
    public:
      ...
      template< typename Other >
      class rebind {
       public:
         typedef Alloc<Other> other;
      };
      ...
   };

   typedef Alloc<int>  AI;
   typedef AI::template rebind<double>::other  Other;  // Compilation error with Visual C++
   \endcode

 * In order to circumvent this compilation error, the WALBERLA_TEMPLATE macro should be used instead
 * the \a template keyword:

   \code
   ...
   typedef AI::WALBERLA_TEMPLATE rebind<double>::other  Other;  // No compilation errors
   \endcode
