0.3.0

In this release, in addition to various performance optimization, small bug fixing, and some internal cleaning-up, the most significant enhancement is the handling of algebraic systems other than the fermion/boson algebra. Currently, Clifford algebra and \(\mathfrak{su}(2)\) algebra are supported. Other algebraic systems should be able to be added with ease.

Also the documentation has been expanded, especially with more examples in the API reference guide. Also the utilities are added for convenient pickling of tensors.
