/*
    CRC++ can be configured by setting various #defines before #including this header file:

        #define crcpp_uint8                             - Specifies the type used to store CRCs that have a width of 8 bits or less.
                                                          This type is not used in CRC calculations. Defaults to ::std::uint8_t.
        #define crcpp_uint16                            - Specifies the type used to store CRCs that have a width between 9 and 16 bits (inclusive).
                                                          This type is not used in CRC calculations. Defaults to ::std::uint16_t.
        #define crcpp_uint32                            - Specifies the type used to store CRCs that have a width between 17 and 32 bits (inclusive).
                                                          This type is not used in CRC calculations. Defaults to ::std::uint32_t.
        #define crcpp_uint64                            - Specifies the type used to store CRCs that have a width between 33 and 64 bits (inclusive).
                                                          This type is not used in CRC calculations. Defaults to ::std::uint64_t.
        #define crcpp_size                              - This type is used for loop iteration and function signatures only. Defaults to ::std::size_t.
        #define CRCPP_USE_NAMESPACE                     - Define to place all CRC++ code within the ::CRCPP namespace.
        #define CRCPP_BRANCHLESS                        - Define to enable a branchless CRC implementation. The branchless implementation uses a single integer
                                                          multiplication in the bit-by-bit calculation instead of a small conditional. The branchless implementation
                                                          may be faster on processor architectures which support single-instruction integer multiplication.
        #define CRCPP_USE_CPP11                         - Define to enables C++11 features (move semantics, constexpr, static_assert, etc.).
        #define CRCPP_INCLUDE_ESOTERIC_CRC_DEFINITIONS  - Define to include definitions for little-used CRCs.
