 * `types.map` - Creates a key based collection type who's children are all of a uniform declared type.
 * If the type stored in a map has an identifier, it is mandatory to store the child under that identifier in the map.
 *
 * This type will always produce [observable maps](https://mobx.js.org/api.html#observablemap)
 *
 * Example:
 * ```ts
 * const Todo = types.model({
 *   id: types.identifier,
 *   task: types.string
 * })
 *
 * const TodoStore = types.model({
 *   todos: types.map(Todo)
 * })
 *
 * const s = TodoStore.create({ todos: {} })
 * unprotect(s)
 * s.todos.set(17, { task: "Grab coffee", id: 17 })
 * s.todos.put({ task: "Grab cookie", id: 18 }) // put will infer key from the identifier
 * console.log(s.todos.get(17).task) // prints: "Grab coffee"
 * ```
