Normally, summary() gives more information than print() would give
for a non-data object, often by manipulations on the object.
Now, the White Book said that summary produces `a synopsis of an object',
but that does not seem to be the practice for model-fitting classes even
in the White Book (but it is for data objects).

Would a more concise print() method be useful? If so the existing print()
could become summary().
