/**

Filter component, interface for filter sigma plugin.
It supposes that sigma graph is already in place, therefore component should not be
mounted until graph is available. It can be used within Sigma component if graph is
preloaded, or within loader component, like NeoCypher.

Filter is hiding all nodes which do not apply to the provided nodesBy criteria.

@param {Nodes$Filter} nodesBy   will hide nodes where filter returns false

type Nodes$Filter = (node: Sigma$Node) => boolean;
