How It Works
------------
When you call `findout` for "foo" with '/bar/baz' as current working directory:
```javascript
findout('foo', {
cwd: '/bar/baz'
})
```
and it will try the following ways,
1. `require('foo')`
2. `require('/bar/baz/foo')`
3. `require('/bar/baz/node_modules/foo')`
4. `require('/bar/foo')`
5. `require('/bar/node_modules/foo')`
6. `require('/foo')`
7. `require('/node_modules/foo')`
If it still can't find any, throws an error.
