Update documentation for STI

[whitespacecode]

Maybe not such a big deal but currently the documentation for Single Table Inheritance makes it that the Models are in one file?
What if you rather have them split in separated model files.

The base entity should have export { Class }
And the derived entity should have an import { Class } from './Class';

Thanks for the hint.

Could you please explain the solution in more detail, I am getting a circular error here:

Parent class:

import Category from "./Category";

export default class Resource extends Model {
static entity = "resources";
...
static types() {
    return {
      CATEGORY: Category,
      ...
    };
}

Sub class

import Resource from "./Resource";

export default class Category extends Resource {
  static entity = "categories";
  static baseEntity = "resources";
   ...
}

You need to use export in the classes also used in circular depenedicies and then import them as seperate module.

import Resource from "./Resource";

export default class Category extends Resource {
  static entity = "categories";
  static baseEntity = "resources";
   ...
}

export { Category }

import { Category } from "./Category";

export default class Resource extends Model {
static entity = "resources";
...
static types() {
    return {
      CATEGORY: Category,
      ...
    };
}
