    Proxy C library for HTTP/s protocol

TECHNICALS 

    * Parsing is carried by a dedicated sub-library which I wrote named parslib.
    * Mass string comparisons are carried by another dedicated sub-library which
    I wrote named streecmp. It runs in O(n) time. n being the lenght of the string - 
    no matter the amount of strings you want to compare it against (I am indeed 
    aware it is nonetheless worse than hashtables - maybe one day I will implement 
    those on my own as well).
