This is a simple Flow-maker that is based on simply algorithm:

We have everything encapsulated in Process that is contains start and end stage:

this is the basic structure of a Process.

If we want to add new stage between two given stage, every stage have both just one Previous and List of Stage for Next stage.

- `Idle`: the object is not touched yet and waiting for flow to touch
- `InProgress`: the object get touch of flow and in progress
- `Reject`: the result of object is reject.
- `Complete`: the result of object is complete and flow can continue into next step.

Proces => StartStage => Intermediate stages => End Stage

When we clone a process then we have following data copied:

ProcessResult => StartStageResult => Intermediate stagesresults => End StageResult
