README
This package provides provides classes and generic operations for additive groups, vector spaces and affine spaces. It also defines a type of infinite towers of generalized derivatives, as described in the paper Beautiful differentiation. A generalized derivative is a linear transformation rather than one of the common concrete representations (scalars, vectors, matrices, ...). The representation of linear maps uses the MemoTrie package.
