Is d_c > d_v or d_c >= d_v ?

From the https://github.com/hichamjanati/pyldpc/blob/master/pyldpc/code.py 

```
 d_c: int, Number of bits in the same parity-check equation. d_c Must be
        greater or equal to d_v and must divide n.
```
and then:

```
    if d_c <= d_v:
        raise ValueError("""d_c must be greater than d_v.""")
```

So what version is correct?
