Update Docs: root models must be Objects and not Strings or Arrays

[quangv]

Root array methods doesn't work.

model.set 'list', []
model.push 'list', 1  # doesn't work

model.set 'list.list', []
model.push 'list.list', 1  # works

Seems like Derby allows root arrays, so the above code should work?

Updated via IRC:

<quangv> i think model.set 'list.items', []   model.push 'list.items', 'test'   works though
<quangv> model roots need to be a namespace or something?
<switz> yes
<switz> list is your id
<switz> therefore if you set list, it has to be an object
<switz> it can't be an array or a string
<switz> or a number
<quangv> hey switz, dang I just filed a bug https://github.com/codeparty/racer/issues/71
<quangv> http://derbyjs.com/#paths  made it seem that fruits : [] is allowed...
<quangv> switz, that's weird so it can't be a string either?
<switz> local models can be strings
<switz> local models are prefaced with _
<switz> and are not saved to the server
<switz> or database
<quangv> so model.set('title', 'Fruit store') shouldn't be used either?
<switz> no
<quangv> i see
<switz> but you can do page.render('index', {title: 'Fruit store'})
<quangv> okay I am going to copy & paste our convo to the bug i just filed and suggest the documentation be changed.
