Improving the performance of FME group based transformers

Some transformers work on one feature at a time, while others work on a group of features. The latter are more resource intensive.

Transformers that have a "group-by" setting are ones that work on groups of features. There are a few ways to improve the performance of these transformers. This demo shows an example of how to improve performance on a transformer, and you'll see how this can greatly reduce memory usage and quicken translations.
