Broken example in README

[spth]

The example in the README has the following line:

printf("node %i has degree %d\n", git.curr);

There are two conversion specifiers (%i and %d) in the call to printf(), but there is only one parameter corresponding to a conversion specifier. Furthermore, both %i and %d expect arguments of type int, but the one argument is of type int64_t.
