### Removes orphan vertices in a simplicial complex

Completely reindexes positions and removes ununsed vertices along the way.

Install

-------

```bash

$ npm install remove-orphan-vertices

```

Usage

-----

```javascript

var removeOrphanVertices = require('remove-orphan-vertices');

var mesh = { 

  cells: [

    [0, 2, 3]

  ],

  positions: [ 

    [0, 0, 0],

    [1, 0, 0], // <- unused

    [1, 0, 0],

    [0, 1, 0],

    [0, 0, 0]  // <- unused

  ] 

}

mesh = removeOrphanVertices(mesh.cells, mesh.positions);

console.log(mesh);

/*

{ 

  cells: [

    [0, 1, 2]

  ],

  positions: [

    [0, 0, 0],

    [1, 0, 0],

    [0, 1, 0]
