Seed for deterministic layout

[dnnsthnnr]

Hi,

currently when the layout is run everytime, then a new layout/order of the the nodes is generated.
Is there a way to apply a specific seed to the layout to have the same results if no nodes/edges are changed?

@dnnsthnnr Unfortunately, current layout doesn't have an option to accept a seed from the user. It can be considered in the future releases.

@hasanbalci Can you point me in the right direction, where this should be implemented. I guess in cose-base or layout-base. Then I can work on it.

@dnnsthnnr the extension code is rather involved, trying to explain its structure and changes needed over Github would be rather inefficient and difficult for all parties involved.

I looked into this for a while and had to try various cytoscape layouts to find one which comes up with a deterministic layout (given the same input graph). Found that the cose-bilkent layout from this repo is in fact deterministic and fcose is not.
