Introduce the StepsGroup concept in the flow

Introduce the StepsGroup concept in the flow. is a way to group a set of steps together, for example :

<StepsGroup Name = "Group01">

<Step>

<name> AssignMessage01</name>

</Step>

<Step>

<name> AssignMessage02</name>

</Step>

<Step>

<name> AssignMessage03</name>

</Step>

<Condition>xyz=123 </Condition>

</StepsGroup>

This will help to :

1- But a single condition for a group of steps ( currently you need to repeat the condition for each step.

2- displaying the flow diagram with the conditions not just a simple one way flow ( currently conditions does not have any reflection on the flow diagram) which will make the interpretation of the flow diagram is a simpler and meaningful
