quickstart: Throwing IOException in the DlogExample

I couldn't compile the example with this error:

➜ scapi-memcpy git:(memcpy) ✗>./install/scapi/bin/scapic DlogExample.java
DlogExample.java:15: error: unreported exception IOException; must be caught or declared to be thrown
        DlogGroup dlog = new OpenSSLDlogECF2m("K-233");
                         ^
1 error
➜ scapi-memcpy git:(memcpy) ✗>

Throwing the IOException there helps to compile it.
