- clef : fix a little bug in storage when evaluating
(was using the wrong trait to deduce storage type).
- gf : block :
- added reinterpret_scalar_valued_gf_as_matrix_valued
for block function
- cleaned make_block_gf_view_from_vector
- added make_block_gf_view_from_vectormake_block_gf_view_from_vector_of_cython_proxy
and changed the cython accordingly because it requires a slightly different syntax.
- updated tests
- gf : cleaned some template.
