Description

This code:

• Adds bindings for casbin::CachedEnforcer
  • The methods added are only the constructors and overrides
  • The rest of the methods are inherited from casbin::Enforcer just like the C++ implementation.
• Adds versioning to pycasbin module through CMake configuration.
• Refactors the workflow by passing the reference of the py::module object to functions.
  • Each function then defines a binding for all the methods present in the corresponding C++ translation unit.

Important Note

When I try to build the pycasbin target, it throws an error wherever there is an occurrence of casbin::Scope in the binding definition. Considering the fact that pycasbin is a client-centric interface, exposing casbin::Scope is redundant, so I dropped the support for Scope in pycasbin.
