Allow definition of nested model relationships with dotted notation

[gsxdsm]

Allow definition of nested model relationships with dotted notation:

obj.model.set({person:{name:'John Doe'}})
can now be addressed with 'person.name' in data bindings as well as
obj.model.get('person.name')

Events are also specified with dotted notation
'change:person.name':function(){}

hmm, we seem to have some indentation issues here - perhaps you're using tabs and not spaces? we use spaces in Agility

This looks good to me, really like those tests. @tristanls ?

[tristanls]

it seems that this would allow setting a property referenced by an empty string:

data-bind=".oops"

which will try to generate a structure of:

model._data[ '' ] = { oops : 'value' };

This is not a bad thing in itself, and perhaps some future convention can have special meaning for variables ".myFoo" as a result of that, just thinking out loud here.

Made a note on code and I'm rusty getting back to ui development, but taking a quick look nothing breaking jumped out.

What about 'person.addresses.0.street', 'person.addresses.1.street' ?
Or better 'person.addresses[0].street' ?
Maybe something like this too : this.model.get('person.addresses.$.street'), to get all streets for example ?
This can be useful as well, what do you think ?

PS: I'm just starting with Agilityjs. I've tested Backbonejs, Knockoutjs, Angularjs, Emberjs, but Agilityjs is the one that fits my way of programming the best. It's really a clever piece of code, thanks Artur. I hope that you will find more time to take care of it.
