Does this JS environment support the `name` property on functions?
## Example
```js
var functionsHaveNames = require('functions-have-names');
var assert = require('assert');
assert.equal(functionsHaveNames(), true); // will be `false` in IE 6-8
```
## Tests
Simply clone the repo, `npm install`, and run `npm test`
