-----------------------------------------------------------

After reviewing the code and seeing that it is possible to implement it cleanly, this jira has been filed. Ot cleanly separates the delay operator code from the regular path, which is majority of our use case. At least few people liked it, so I am documenting the idea.

> One of the design elements I have seen in Apex is, while deploying only required objects are deployed. For example Stream persistence reservoir was created only when it is required. So in the same spirit, we can have the DelayNode for Delay Operators.
> Delay Operator related changes happen for the control tuples in GenericNode.
> Implementation Idea: 
> 1. Create functions for handling each control tuples in Generic Node
> 2. DelayNode extends GenericNode
> 3. Overrides the required functions created in step 1.
> 4. During deployment based on the operator type, create the required Node.
