Description

Major revamp to our angular generator, contains:

• handle complex attributes by creating a class variable (state) instead of hacky useObjectWrapper etc to solve angular not able to properly handle complex js code inside template
• dynamic props for dynamic components support
• auto-reactivity for all props
• handle complex code inside for For
• all the changes are behind a feature-flag called class-properties
