[TIMOB-13425] Ti.UI.create(): An applyProperties-like way to create a whole view hierarchy at once

// Ti.UI.create returns some kind of view-collection object
var views = Ti.UI.create({
  'Window': {
    fullscreen: false,
    backgroundColor: '#fff',

    // Non-hierarchy views can also be added like:
    titleControl: {
      'Label': {
        text: 'My title',
        font: { fontWeight: 'bold' }
      }
    },
    
    // Child views are added through a 'children' property
    children: [
      {
        'View': {

          // Only views that have an 'id' can be referenced in JS-land through a proxy object
          id: 'red',
          
          top: 100, left: 50,
          width: 200, height: 200,
          backgroundColor: '#f00',
          
          children: [
            'Label': {
              id: 'platform',

              // In Alloy this wouldn't be needed since platform branching is done at built-time,
              // but for usage without Alloy this would be really nice to have.
              platform: ['android'],
            
              top: 25, right: 25, bottom: 25, left: 25,
              backgroundColor: '#0f0',
              
              text: 'I am green Android'
            },
            'Label': {
              id: 'platform',
              platform: ['ios'],
              
              top: 25, right: 25, bottom: 25, left: 25,
              backgroundColor: '#00f',
              
              text: 'I am blue iOS'
            },

            // You could also include an existing Ti.UI object like this:
            someExistingView
          ]
        }
      },
      {
        'Label': {
          top: 400, left: 0, right: 0,
          height: Ti.UI.SIZE,
          
          text: 'I want Ti.UI.create()',

          // Events could also be added like this, but
          // it would compromise clear controller-view-separation
          onClick: myCallback,

          // Just like platform-branching, formFactor would be like:
          formFactor: ['tablet']
        }
      }
    ]
  }
});

// Views that have an 'id' can be referenced from JS-land
var redView = views.get('redView');

// Views you won't need anymore can be destroyed, including children
views.release('platform');

// Or just release all
views.release();
