/**
* \file util.hpp
*
* \brief Utility macros/functions for testing and debugging purpose.
*
* Basic usage:
* <pre>
* BOOST_UBLAS_TEST_DEF( test_case_1 )
* {
* // do your test stuff
* }
*
* BOOST_UBLAS_TEST_DEF( test_case_2 )
* {
* // do your test stuff
* }
*
* // ...
*
* BOOST_UBLAS_TEST_DEF( test_case_n )
* {
* // do your test stuff
* }
*
* int main()
* {
* BOOST_UBLAS_TEST_SUITE( "My Test Suite" ); // optional
*
* BOOST_UBLAS_TEST_BEGIN();
* BOOST_UBLAS_TEST_DO( test_case_1 );
* BOOST_UBLAS_TEST_DO( test_case_2 );
* // ...
* BOOST_UBLAS_TEST_DO( test_case_n );
* BOOST_UBLAS_TEST_END();
* }
* </pre>
* Inside each <em>test_case_<code>k</code></em> you can use the various
* \c BOOST_UBLAS_TEST_CHECK* macros.
