Let us assume that a tensor context includes N + 1 tensors.
Then, HDF5 export will generate a HDF5 file whose structure is given as follows:
[value group]/
[file 0] <- A dataset that contains the value of 1st (=0) tensor
[file 1]
...
[file N]
[name group]/
[file 0] <- An attribute that contains the name of 1st (=0) tensor
[file 1]
...
[file N]
