/**
 * @module intro
 * @description
 *
 * Types are the building blocks of `papr` [schemas](schema.md), which provide TypeScript type definitions,
 * as well as the ability to generate [JSON schema](https://docs.mongodb.com/manual/core/schema-validation/#json-schema)
 * for validators in MongoDB collections.
 *
 * Some types have additional options, based on the available options from JSON schema for that data type.
 *
 * The following data types are available to define the schemas of your `papr` models:
 */
/**
 * The following type creator functions return valid JSON schema definitions at runtime,
 * however for TypeScript they return actual TypeScript types.
 *
 * To workaround this difference between runtime and type-checking, we use the pattern `return X as unknown as Y`;
 *
 * All type creator functions below return a `$required` attribute, which is used only internally
 * to compute the `required` keys array in the containing parent object.
 *
 * This `$required` value is removed in the `createSchemaType` function.
