Converts a bunch of functions into a method-chainable calss with a shared data model.

Context

Don't care.

Parameters

functions/mix-ins

Any number of named functions or objects with methods. Note that functions can't be anonymous or will throw Error. All functions must take first argument as a data model object (or so called "object-based" functions) and return a (new) data model object.

Example

Pass named functions:

var _ = require('lodash');
var chainify = require('model-chainify');
var Collection = chainify(_.flatten, _.uniq, _.sortBy);
var collection = new Collection([1, 2, [4, 3, 2]]);
collection.flatten().uniq().sortBy().get(); // => [1, 2, 3, 4]

Pass mix-ins Object:

var _ = require('lodash');
var chainify = require('model-chainify');
var Collection = chainify({
	flatten: _.flatten,
	unique: _.uniq,
	sort: _.sortBy
});
var collection = new Collection([1, 2, [4, 3, 2]]);
collection.flatten().unique().sort().get(); // => [1, 2, 3, 4]
