Defines a part of a form that cannot be divided into other controls.
Controls have values and validation state, which is determined by an
optional validation function.
Control is one of the three fundamental building blocks used to define
forms in Angular, along with ControlGroup and ControlArray.
Usage
By default, a Control is created for every <input> or other form
component.
With NgFormControl or NgFormModel an existing Control can be
bound to a DOM element instead. This Control can be configured with a
custom validation function.
