std::string sequant::detail::basis_instance_tag(const Index &idx)

Returns:

the basis instance of idx in decimal, with _ in place of the minus sign of a negative one (so it is valid in an identifier and, unlike a letter, cannot be read as the tag of a space), to append to a block tag or dimension name of a mode in that basis; empty if idx has none
