/* Usage:

1. Define an assertion class, derived from vigra::staticAssert::Assert,
   whose name serves as an error message:
   
    template <int N>
    struct FixedPoint_overflow_error__More_than_31_bits_requested
    : vigra::staticAssert::AssertBool<(N < 32)>
    {};

2. Call VIGRA_STATIC_ASSERT() with the assertion class:

    template <int N>
    void test()
    {
        // signal error if N > 31
        VIGRA_STATIC_ASSERT((FixedPoint_overflow_error__More_than_31_bits_requested<N>));
    }
    
TODO: provide more assertion base classes for other (non boolean) types of tests
