Functional pipes and promise based pipes.

```javascript

const assert = require('assert');

const {pipe, promisePipe} = require('..');

describe('test', () => {

    it('pipe', () => {

        let addOne = (it) => it + 1;

        let addTwo = (it) => it + 2;

        let xpipe = pipe(addOne, addTwo);

        assert.equal(xpipe('hello'), 'hello12');

        assert.equal(xpipe(5), 8);

    });

    it('pipe / array constructor', () => {

        let addOne = (it) => it + 1;

        let addTwo = (it) => it + 2;

        let xpipe = pipe([addOne, addTwo], addOne, [addTwo, addTwo]);

        assert.equal(xpipe('hello'), 'hello12122');

        assert.equal(xpipe(10), 18);

    });
