All OpenFHE objects (CryptoContext, Ciphertext, Plaintext, Keys, etc.) inherit from this class. It holds an external pointer to a C++ shared_ptr.
Value
An S7 object of class OpenFHEObject, the base class every object
in this package inherits from. It has a single property, ptr,
holding an external pointer to the underlying C++ shared_ptr.
Constructing one directly is of no use; the class exists so that
methods can dispatch on the common parent and so that the pointer is
managed in one place.
