Detailed Description

Description: This class holds a ProductIndexHolder and a boolean value to indicate whether the skipCurrentProcess option was set. Internally it bit packs them in an unsigned int. There is a little extra complexity in the implementation to hide the fact that some special values of ProductHolderIndex use the same bit we use for skipCurrentProcess.

Usage: EDConsumerBase use this and pass a container of them to the Workers to let them know what data will be consumed.
