    The generated code uses the copyFromSafe methods in code generated copiers. Your copyEntry
method which is used by the GenericCopiers also uses the copyFromSafe method. So we should
inherit all the same supported types. I think if all the unit tests, functional tests, and
QA tests pass that will be a sufficient enough vote of confidence. Ideally we would have unit
tests for all the operators (not just the copiers) which use the complex data types, but there
is significant amount of work left to be able to effectively unit tests with complex data
types and adding all the machinery to do so is out of the scope of this PR.

> Currently the copier can only copy record from an incoming batch to the beginning of
an outgoing batch. We need to be able to copy a record and append it to the end of the outgoing
batch.
