Allow default use without the need of a model

### Expected Behaviour

Currently the library requires a model to be defined in order to parse the DOM into React properties.
We could add a default mode without the need to specify a model.
Every time a property of the element changes the library can update the React component with a property named after the attribute name and with the value as string.

We could consider transforming attribute with hypens (-) to camel case.

首先阅读仓库中基于模型的 DOM 解析和 React 属性更新的 JavaScript 实现。定义无模型运行时的预期行为，包括带连字符的属性是否会转换为 camel case，然后验证更改元素属性会使用该属性名和字符串值更新 React 组件。
