ublas/doc/samples/Jamfile.v2: added build section for ex_triangular ublas/doc/container_concept.htm: fixed wrong description of array_type ublas/doc/triangular.htm: fixed lower/upper confusion and added link to ex_triangular ublas/test/test_lu.cpp: added unit test for LU decomposition ublas/test/triangular_access.cpp: added unit test for accessing triangular/symmetric matrices ublas/test/triangular_layout.cpp: added unit test for testing storage layout of triangular/symmetric matrices ublas/test/common/testhelper.hpp: support routines for new unit tests ublas/test/CMakeLists.txt: added new tests (still experimental) test_lu, triangular_access. triangular_layout ublas/test/Jamfile.v2: added new tests (still experimental) test_lu, triangular_access. triangular_layout disabled broken test7 (maybe a fix of boost::interval is needed, see #2473) ublas/test/test71.cpp, ublas/test/test73.cpp, ublas/test/test7.cpp: added first fixes to support boost::interval as scalar type ublas/test/common/init.hpp: initialize all matrices/vectors with floats instead of (unsigned) ints this helps to fix broken test7 for boost::interval [SVN r52147]
