AttributeExistenceChecker for FME

This is a custom transformer for FME that checks whether an attribute actually exists and routes features accordingly. This is useful because certain formats only attach attributes to a feature if the feature actually has a value for that attribute. This sometimes causes problems with transformers such as the Joiner. Hence by using the AttritubeExistenceChecker you can find out which features are affected, and deal with them seperately.
