Complete the following function in C

To complete the code in `lfsr.c` and produce a working LFSR you need to write two functions. These are the `read_lfsr` and `next_state` functions shown below.

``` int read_lfsr(LFSR* L) { /*Return the current output bit (the rightmost bit of the state variable) */

/* You implement this*/

return 0; // remove this line when you properly implement the function.

}

As described in the comments, the `read_lfsr` function should return the rightmost bit of the LFSR `state` variable. Note that `L` is passed as a pointer, so the `state` field must be accessed as `L->state` not `L.state`.
