Instructions

Make answers to the following problems below using PHP. For now, you can psuedocode the methods with comments, or you can create your own implementations if you feel adventurous.

	api.find = function (model, options, conditions) {
	console.info(options); // {limit: 1}
	return new RSVP.Promise(function (resolve, reject) {

	var options = options \|\| {},
	defaults = {
	limit: null,
	offset: null,
	orderBy: null,
	direction: null

	* ### Usage

	* ```javascript
	* // Some function you want to partially apply
	* function someFunc(a, b, c, d) {return arguments;}

	* // Curry the function

	var user = ORM.factory('user');

	user.where(function (user) {
	user.where('id').between(1, 10);
	}).orWhere(function (user) {
	user.where('id').between(100, 200);
	}).orWhere({
	active: true,
	banned: false
	}).findAll();

	/**
	* This is a WIP of potential usage of the ORM in a NodeJS implementation. Let's try implementing
	* this as a module for other parts of the app to use. Less instantiation for later

	repository = require('awesomeorm-repository-rest')('http://rest.example.com/schema'),
	dataParser = require('awesomeorm-data-jsonapi'),
