Slowly forward

-> Type conventions
-> Little macros (for internal use)
-> Level uint based, multiples of 2 (allows concat of diferent levels,
yeah!)
-> namespace help -> namespace utils
-> Smart mutex (derivated of std::mutex, added lambda for auto
lock-unlock)
-> Test of Writer class. WIP
-> Test of Logger class. WIP
-> Test of Manager class. WIP!
-> Change to std::unique_ptr for global var holding
-> Boilerplate for Config class. WIP
-> Macros for easy Level access (el::ERROR, el::DEBUG...)
-> Boilerplate / WIP of LOG global function
