Centralized configuration

[skal111]

Hi,

Thx a lot for the nzToggle library which I intensively use.

Since I have many nzToggle elements in my application it would be great if I could define a default configuration for my toggles as they all share the same color and size properties.

Could be something like this

angular.module('myModule', [nzToggle]).config([ 'nzToggleConfigProvider', function(nzToggleConfigProvider))
{
nzToggleConfigProvider.setTrueColor('#123456');
nzToggleConfigProvider.setWidth('20');
...
...
}
