Checks a React component to see if it has any children in props.

Returns a boolean which indicates if the provided anyComponentOrClass parameter is an instance of React.Component (if passed an object) or a class derived from React.Component (if passed a function) or a component derived from React.Component.

In a command line interface, where focusable controls exist (think Visual Basic for DOS) to get an idea of the concept, we can't completely blur out of EVERY single control.

Something is always going to ALWAYS need to be accept / capture input, be it a Button or TextField or a Menu or a Tab or Tree. But the concept of the Control component is that it can easily allow focus to shift from one component to the next, and allow those components which extend the Control class to easily display one type of blurred output while accepting input once focused.

In order to guarantee this, blur will locate the forward (or reverse component) and 'select' it instead.

Returns a boolean which indicates if the Control instance is un-focusable.

Returns a boolean which indicates if a Control instance is focusable.

The isBlurred() method returns the inverse of the isFocused() method.

The isDisabled() method returns a boolean which indicates the value of the disabled property as passed into the component.

The isEnabled() method returns the inverse value of the isDisabled() method.

The isFocusable() method returns a boolean which indicates the value of the field, focusable.

The isFocused() method returns a boolean which indicates the value of the focused property as passed into the component, as long as it is not disabled.
