React Make RadioButtons -- Introduces Properties

Extend the react Component Class to make a dynamic radio button with label.

• We want to re-use the class code so we make the value and text based on component properties that we can change.
• The properties will be the value, the text, the name and the id.
• In the definition of the extended class the properties are referred to as {this.props.groupName}
• When invoking the component the properties are set to specific values as groupName="size"
• Because in JSX/Babel we are mixing HTML and JavaScript we have to be careful of keywords used by each. Thus we replace the HTML for, used to make the label and radio input work as a unit, with htmlFor

Sizes
