- An error occurred while linking the `RdmaAllocator` library to the `warm_benchmark` program.

```

- Checking the argument and parameter types helped resolve the linking error.
- Inline functions are recommended to be merged into header files to allow for their optimization by the compiler.

- Compiled successfully without any errors.
- Add allocator implementation in rfaaslib.
- Encapsulate the memory registration in rdmalib
- Add test demonstrating standard memory allocation.

- Add a `construct` method in `rdmaAllocator.hpp` to enable allocation with std::vector.
- Test demonstrating standard memory allocation practices.
- Test demonstrating allocation with our custom allocator.
- Test demonstrating allocation with std::vector.
- Improve coding style and adhering to clang-tidy standards.
