Detailed Description

Reimplementation of the std::fstream class.

This implementation is buffered, meanding that the class will keep a read and a writebuffer, and only perform disc accesses if neccessary.

This reimplementation performs way better in the usecase, that seekp/seekg is called often. The std::fstream implementation discards its buffer every time seek is called, resulting in a horrible runtime performance in our usecase.
