- For users : only change is : H5::H5File in apps. to be replaced by triqs::h5::file, same API. - using only the C API because : - it is cleaner, better documented, more examples. - it is the native hdf5 interface. - simplify the installation e.g. on mac. Indeed, hdf5 is usually installed without C++ interface, which is optional. E.g. EPD et al., brew by default. Also the infamous mpi+ hdf5_cpp bug, for which we have no clean solution. - clean the notion of parent of a group. Not needed, better iterate function in C LT API. - modified doc : no need for C++ bindings any more. - modified cmake to avoid requiring CPP bindings.
