Swimlane layout added to smart-layouts feature 

Raised by SH/RH on Operating Model Visualisation use case.

As a modeller, I want to be able to select a set of content on a model canvas, and automatically layout the content as a swimlane diagram so that I am able to create diagrams with reduced effort, reducing the cost to maintain or create COMPASS type solutions. 

Acceptance criteria are that I am able to select a set of elements, with relationships between them. The model will layout into a swimlane style, respecting a set of pre-defined constructs. I accept I must be able to differentiate the types of relationship between those which are process>process and those which are role>process 

OR 

As a modeller I want to be able to select a set of content on a model canvas and select a layout style to be applied to the content with respect to its group or swimlane, so I can quickly and easily layout a model that uses swimlanes. 

Acceptance criteria when selecting elements and a layotu option I can choose or it automatically lays them out with their groups/container/swim lanes not as a whole. So I can select all elements and then ask them to align to the center and they will all center within their swim lane not with each other.
