TECHNICALS

    struct nod 
        * data structure that represents a node of the tree
    struct nod *mknod(struct nod *prnt)
        * create a child node below given parent node 
        * returns: pointer to said node or NULL if function fails
    int mkstr(struct nod *rot, char *str)
        * fit string into tree if it does not already exist
        * warning: string has to be null-byte terminated 
        * returns: the assigned ID of the string, 0 if string 
            is already inside tree, or -1 if function fails
    int gentree(struct nod *rot, char *strs)
        * generate tree from character seperated strings
        * warning: seperation character is '\n'
        * returns: 0 if ok or -1 if function fails
    int streecmp(struct nod *rot, char *str) 
        * traverse tree and search for str
        * returns: id of string or 0 if there is no match

TODO

    * Memory leaks
    * Alloc/free functions
    * NULL checking
    * Memset for initialization
    * gentree with custom seperator
