Implementation of so called Strong PUF

All interfaces required for authentication are in PUF.h. Each instance of PUF class is a stable circuit. Each stable circuit
consists of random ES boxes. randomness to generate functions.
See main.cpp for an example. Each step of the authentication process is also available publicly.
Puf puf; // Initialize the circuits with fresh randomness
puf.Auth(bitset<128> S); // Authenticate S. S is a std::bitset of size 128
puf.Stage_1(bitset<128> S); // Output 64 bits as the output of stage 1
puf.Stage_2(bitset<128> S); // Output 64 bits as the output of stage 2
puf.Sbox(bitset<128> S); // Performs 16 AES sboxes on 16 bytes.
Generating the required input for the Sbox layer and computing the final result is implemented in the
Pum::Auth() function.
