5% Save the given variables in an hdf5 file in the groupe given by the
6% prefix. If new is set to one creates a new hdf5 file. Syntax Similar to
7% the native matlab save command. Can save strings, arrays, and structs.
8% If it find a struct it calls its recusively to save the struct, passing
9% the struct name as the prefix.
