Using awesome [Ant Design](https://ant.design/) for widgets

11+
### Features
12+
- Highly configurable
13+
- Fields can be of type:
14+
- simple (string, number, bool, date/time/datetime, list)
15+
- structs (will be displayed in selectbox as tree of members)
16+
- custom type (dev should add its own widget component for this) (it's not complex, you can add slider for example)
17+
- Comparison operators can be:
18+
- binary (== != < > ..)
19+
- unary (is empty, is null)
20+
- 'between' (for numbers)
21+
- complex operators like 'proximity'
22+
- Values of fields can be compared with values -or- another fields (of same type)
23+
- Reordering support for rules and groups of rules
24+
- Using awesome [Ant Design](https://ant.design/)
25+
