Description

Currently we use both.

For what it's worth, my vote is for google-collections (which is now a subset of guava) rather than the Apache commons collections. Two reasons:
1. I think it's better quality
2. the guava library is likely to give us some further general language utilities, meaning we can may be able to delete some stuff in org.apache.isis.core.commons.
