XML to JSON and DSL for ConstraintSet attributes

XML for ConstraintSet has many attributes because of the way XML works. Many of them have been combined for example android:layout_width, layout_constraintWidth, layout_constrainedWidth, layout_constraintWidth_min, layout_constraintWidth_max, layout_constraintWidth_percent, and layout_constraintDimensionRatio are all combined in width:

{
  width: 23,
  width: 'spread',
  width: { value: 'wrap', max: 300 }
}

1* - By convention helpers will be explicitly vertical or horizontal (vBarrier or hBarrier)
2* - The id is usually the label 
MotionLayout* - These features of MotionLayout are not implemented.

Helpers flow, barrier are not implemented
