Write Custom Specification

1. Write a TdZdd-specification in src/spec/*.hpp
2. Let the new specification class be A, wrap the following classes and methods in src/wrapper.cpp
   • tdzdd::DdSpecBase<A, 2>
   • tdzdd::DdSpec<A, T, 2>
   • A
   • tdzdd::DdStructure<2>::zddSubset<A>
3. import _pyzdd.A in pyzdd/__init__.py
