[DEVELOPMENT] PlanePlot

[marnec]

Brief explanation
an api to easily draw a Plane from 3 points

Details
PlanePlot should be a class implementing Frameable that draws a semitransparent plane. The intended usage of the plot is to section the 3d space (e.g. to visually separate groups of points).

Later I intend to offer an api to draw more elaborate surfaces, but the aim of the PlanePlot is to offer the simplest possible interface to draw a plane.

Simplicity is also the reason of the name: PlanPlot is lame but it is immediately obvious what this plot is for. I'll go for clarity above all, I vastly prefer when apis are self-explanatory

Notes
Required parameters to draw the PlanePlot ideally are 3 points, as they are the minimum defintion of a plane in 3d space.

const plane = new THREE.Plane();
plane.setFromCoplanarPoints(v1,v2,v3);
