- clean array, matrix, vector expression template they take const & of objects, or move && objects no more views. -> C++11 modernisation - Fix a bug in array resize : it was resetting the indexmap to C memory layout e.g. for a fortran array - Fix a bug in read h5 array when not in C order (forgot an else, the array was read twice).
