Usage

Return an object instance of an object with only certain feature accessable directly:

var slimApi = require('slim-api');

var original;
var newObj;

function Original() {
    this.inventory = 3;
}

Original.prototype.setInventory = function(num) {
    this.inventory = num;
}

Original.prototype.getInventory = function() {
    return this.inventory;
}

original = new Original();

newObj = slimApi(original, ['setInventory', 'getInventory']);

console.log(newObj.getInventory()) // 3
newObj.setInventory(9)
console.log(newObj.getInventory()) // 9
console.log(newObj.inventory) // undefined

functions can still be applied to other contexts:

var word;
var newObj;
var target;

function Word() {
    this.letters = ['t', 'e', 's', 't'];
}

Word.prototype.alphabetize = function () {
    return this.letters.sort();
}

word = new Word();

newObj = slimApi(word, ['alphabetize']);

target = {
    letters: ['t','a','r','g', 'e', 't']
}

console.log(newObj.alphabetize()) // ['e','s','t','t']
console.log(newObj.alphabetize.call(target)) // ['a','e','g','r','t','t'])
