Rewrite in NodeJS the Chase's Twiddle algorithm that returns all combinations
of m out of n objects.

The C implementation can be found
here.

API

$3

``javascript
const NodeTwiddle = require('node-twiddle');
`

$3

`javascript
const twiddle = new NodeTwiddle(n, m);
`

where n is total number of objects, m is number of objects in each
combination.

$3

`javascript
twiddle.genAllCombs(input)
`

where input is an optional parameter for array of n objects. Hence, output
is all combination of m out of the n objects. If the input is not given,
output is an array of all sequences of 0's and 1's containing m 1's.

$3

Initialize parameters for iterating

`javascript
const params = twiddle.init(input)
`

The input parameter is optional as described above.

The 1st combination is params.res. Each next combination is iterated via

`javascript
twiddle.iterate(params)
`

If it returns undefined`, the iteration ends.
