Using form name arrays without defined key name causes a TypeError.

[jakeandreoli]

I found an issue when trying to use array values without a defined key name. This can be easily replicated.

I am unsure if this is an issue in the wrapper or the original code, though the error occurs in the reconcile function, which is not present in the synchronous version; hence why I am sharing the issue here.

<input type="password" name="password[]"> <!-- Should be treated as password[0] -->
<input type="password" name="password[]"> <!-- Should be treated as password[1] -->

The actual error occurring:

TypeError: Cannot create property 'undefined' on string ''

Putting the following works around the issue, however creates problems when dynamically creating elements based on user interaction:

<input type="password" name="password[0]">
<input type="password" name="password[1]">

I added a pull request that adds support for this #22 and refactored code to allow this to work.

Hi @jakeandreoli, thanks for the PR. I've merged #20 to address this problem. I will keep you PR open for now as it might come in handy later.
