+    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 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 or -1 if 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 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
+
+    * Characters "hashmap" to remove linear checking of children nodes 
+    * Remove memory leaks
+    * Add alloc/free functions
+    * NULL checking

+COMMITS
+    
+    Each commit is prefixed with an indicator token of what the change is
+    *mostly* about. List of tokens is: 
+    
+        * repo: change docs or code style
+        * feat: implement new change
