Serializes the specified event into the specified event message.
make a char* as a data member, tell ROOT to not adapt it, but still use it. initialize it to 1M, let ROOT resize if it wants, then delete it in the dtor.
change the call to not take an eventMessage, add a member function to return the address of the place that ROOT wrote the serialized data.
return the length of the serialized object and the actual length if compression has been done (may want to cache these lengths in this object instead.
the caller will need to copy the data from this object to its final destination in the EventMsgBuilder.
