I'm looking for some Sample APEX that would, upon Case creation, do a lookup to the Contacts Account and find the Entitlement Associated to the Account.  In my case, there will only ever be one Entitlement associated to an Account so the results would return one record.  I need this entitlement to be automatically associated to the Case and automatically kick off.  Essentially, when a case is created, I need the entitlement to kick off immediately.  Does anyone have any sample APEX I can look at that might point me in the right direction.
