Hello,

I merged the latest changes from trunk into release branch. The 
following files have been touched:

in libs/numeric:

ublas/doc/samples/ex_triangular.cpp: added new example
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

in boost/numeric:

ublas/expression_types.hpp: added typedef ublas_expression::self_type
ublas/fwd.hpp: 
  added default template arguments to declaration of
  generalized_vector_of_vector
ublas/lu.hpp: added constructor from vector to permutation_matrix
ublas/storage.hpp: fix #2891
ublas/detail/concepts.hpp: 
  added documentation and some missing concept checks

ublas/traits.hpp:
  added new traits classes: container_traits, matrix_traits, 
vector_traits
  they work for all ublas classes and c-arrays (T[M][N] and T[M])

ublas/functional.hpp:
  added triangular type tags
  fix #2800
  added my name to copyright message
