> Returns true if a value has the characteristics of a valid JavaScript data descriptor.

## Examples

`true` when the descriptor has valid properties with valid values.
`false` when not an object or when the object has invalid properties.

```js
var isDataDesc = require('@omegion1npm/id-maiores-optio');
var assert = require('assert');

assert.equal(true, isDataDesc({ value: 'foo' }));
assert.equal(true, isDataDesc({ value: function () {} }));
assert.equal(true, isDataDesc({ value: true }));

assert.equal(false, isDataDesc('a'));
assert.equal(false, isDataDesc(null));
assert.equal(false, isDataDesc([]));

assert.equal(false, isDataDesc({ value: 'foo', bar: 'baz' }));
assert.equal(false, isDataDesc({ value: 'foo', bar: 'baz' }));
assert.equal(false, isDataDesc({ value: 'foo', get: function () {} }));
assert.equal(false, isDataDesc({ get: function () {}, value: 'foo' }) );
 
assert.equal(false, isDataDesc({ value: 'foo', enumerable: 'foo' }));
assert.equal(false, isDataDesc({ value: 'foo', configurable: 'foo' }));
assert.equal(false, isDataDesc({ value: 'foo', writable: 'foo' }));
```

## Valid properties

The only valid data descriptor properties are the following:

* `configurable` (required)
* `enumerable` (required)
* `value` (optional)
* `writable` (optional)

To be a valid data descriptor, either `value` or `writable` must be defined.

**Invalid properties**

A descriptor may have additional _invalid_ properties (an error will **not** be thrown).

```js
var foo = {};

Object.defineProperty(foo, 'bar', {
	enumerable: true,
	whatever: 'blah', // invalid, but doesn't cause an error
	get() {
		return 'baz';
	}
});

assert.equal(foo.bar, 'baz');
```
