Andrea C updated TINKERPOP-3150:
--------------------------------
Description:
Sample step will ignore previous by modulators if multiple are specified, which
can be misleading to the user. Instead, similar to
https://issues.apache.org/jira/browse/TINKERPOP-3121 multiple by modulators
should be prevented with sample.

Aggregate step will ignore previous by modulators if multiple are specified,
which can be misleading to the user. Instead, similar to
https://issues.apache.org/jira/browse/TINKERPOP-3121 multiple by modulators
should be prevented with aggregate.
