Detailed Description

Represent an associative op with its identity.

The op may be multi-dimensional, e.g. complex multiplication. 'is_commutative' is set to true if the op is also commutative in addition to being associative.

For example, complex multiplication is represented as:

AssociativePattern pattern(
   {x0 * y0 - x1 * y1, x1 * y0 + x0 * y1},
   {one, zero},
   true
);
