This is the base class for
Controlclasses (i.e. FormControl),It provides some of the shared behavior that all controls and groups of controls have, like running validators, calculating status, and resetting state. It also defines the properties that are shared between all sub-classes, like
value,valid, anddirty. It shouldn't be instantiated directly.NOTE: Heavily borrowed from Angular's AbstractControl: https://github.com/angular/angular/blob/5dcdbfcba934a930468aec140a7183b034466bdf/packages/forms/src/model/abstract_model.ts
