Title: norm_inf to answer issue #758

just norm_inf for now

that is :
max(abs(a)) for a vector
max(sum(abs(a), 2)) for a matrix

norm_inf can be used as
norm_inf(a)
norm_inf(a, nt2::vector_)
norm_inf(a, nt2::matrix_)

the second parameter can be used to suppose (with vector_) a is always a big column vector
or (with matrix_ ) a is always matrix.

Joel does that fit ?
