Layout auto render

[cerencimer]

Each time the state changes the cytoscape layout is rendered again. I don't want to change position of the nodes. Is this due to the react-cytoscape component? If user changes node positions, this changes should be stored. Also, I could not get current position of nodes. The component's layout options and cyRef's layout options are different. If I want to get layout from cy, I count not get layout that is null.
