Typescript definition for node/edge data

[sim51]

Program process function

Sigma allows developer to create node's program, but the definition of the NodeDisplayData can't be extended.

For example, if I want to write a program that do a circle and a border with their color and size managed by the data, it's not possible. I can't add the attributs borderSize and borderColor for example.

For now, TS allows to extend the NodeDisplayData in program's process function.

export default class NodeProgramBorder extends AbstractNodeProgram {
  ...
  process(
      data: NodeDisplayData & { borderSize?: number; borderColor?: string },
      hidden: boolean,
      offset: number
    ): void {
   ...
  }
...
}

TS compile, even if in pure object conception, it should not.

Propagation of the graph type

The graph types are not propagated deeply in the code base of sigma, like in the node/edge reducer for example

@sim51 has recently worked on that for v3, there is a branch v3-graph-typing with an implementation, that should be shipped with next v3 alpha or beta release.
