Coding Style

It would be great if we could all follow the same coding style.

For ompparser written in C++, C++ Core Guidelines is strongly recommended since it's a collaborative effort led by Bjarne Stroustrup. Google C++ Style Guide is also a good reference.

For example, assume there's a regular variable in the main function that represents the amount of input files. Then input_file_amount should be used rather than inputFileAmount. It's not about correctness but unified coding style in the team.
