Better validation of input

[gr0uch]

Validation should be more strict and/or more informative. Examples:

/* I think there should be some sort of warning
   for trying to pass in an object, or if there is a
   clear type mismatch */
balanced.bankAccount.create({
  name: 1010001101010,
  routing_number: 123123123,
  account_number: {
    'omg': 'wtfbbq'
  }
}, function(res) {...}); // 201

/* same issue with functions, it makes the request
   though it does not serialize the `account_number`
   and thus it errors, could have been prevented */
balanced.bankAccount.create({
  name: 'foo bar',
  routing_number: 123123123,
  account_number: function(){}
}, function(res) {...}); // 400

/* it would be nice if `create` could return a promise using
   some lightweight promises lib that implements promises/A+ */
var promise = balanced.bankAccount.create({
  name: 'foo bar',
  routing_number: 123123123,
  account_number: 58294368
}); // cryptic error message due to minification, needs callback function parameter

balanced.bankAccount.create('foo'); // yay cryptic error

1. library should not be minified - https://js.balancedpayments.com - let's make a new issue to un-minify that
2. if you pass a function should we try and evaluate the response?
3. by warning what do you mean? console.warn or something in the callback?
4. I agree that promise could be nice.

1.) It would be nice to build an unminified version, but we should also not encourage its use in production. 2.) I don't think so, that would be too magical. 3.) console.warn should be sufficient. 4.) What about using Q or RSVP.js? they're both ~2.5kb minified+gzipped.
